My first modification after buying my G0602 was to add a Quick Change Tool Post. QCTP's have many advantages, including quick and easy tool changes, consistant tool height setting, and safety (sharp tools sticking out in 4 directions from a standard 4-way tool post can be a painful way to learn a lesson!).
Anyway, adding a QCTP to the G0602 is very simple, as long as you access to a milling machine to mill the plate that fits in the t-slot. Here's a video of the process.
If you don't have a milling machine you could figure out a way to hold the plate in your 4-way tool post and use an end mill held in the chuck (or better yet held in an end mill holder that fits the taper of your lathe spindle). But you're best bet is to use a mill to modify the plate to fit your t-slot.
One final thing, your QCTP probably came with a plate to modify as mine did. But my plate was a bit short, so I fabricated my own out of a piece of scrap. Doing so requires you to also have a proper tap handy. That tap size may vary depending on who made your QCTP, but just keep that in mind if you decide to make your own plate rather than modify the one the tool post comes with. I purchased my tap for about $12 from a local supplier (no shipping). You could probably get one for about the same price from an online supplier + shipping. If it's a size you think you'll use a lot moving forward, go ahead and purchase a high-quality tap. But if not, go with a cheap tap. I haven't used my tap since adding the QCTP over two years ago, so the cheapest tap they made was perfect!
As an alternative to buying a tap, you could also single point the internal threads on the plate, but that's a whole 'nother ball of wax, and somewhat outside of the scope of a beginner-level modification. But if someone does single point their plate, please post a comment with pictures &/or video of your modification.

Tyler great info i made a new post for mine using a piece of 5/8" round stock. first brought down to size then single pointing the threads on both ends. which in my post i stated the wrong thread size for the stock plate there m10 x 1.5
didnt turn out too bad but i didnt take any while i was doing it
Post on the left was the one that came with the QCTP from CDCO
stock plate on top then my tool post notice shorter over all length and longer length of threads
the M10 threads are really tricky to cut the carriage feed is very fast especially for the short distance you will be cutting. i ended up using a die to cut them
sorry for the bad photos i took them with my phone

My local hardware store had M14x1.25 and M14x2.0 taps, but didn't have the M14x1.5 tap. Dang.

luckily i thought of it right before i placed an order with northern tools for some cutting fluid and metric drill bits. i think it was like $10 there for it.
got my lathe and bandsaw in today. bandsaw is setup and i took some stuff off the lathe to get started on cleaning it up so i am closer to being ready to use it when i have a buddy come help me get it on the workbench. and holy crap people werent joking when they said the chuck is stuck on there, i tried for a couple mins and quick cuz i knew it would get me all pissed off. time to look at all the ways people did it and come up with a new plan.

chuck a length of stock in the chuck some use a 2 x 4 i used a 1/2" x 48" square stock. making a spanner wrench is best but anything in the spindle hole will work i used a hardened drive pin then used a piece of 1 x 4 to protect the ways of the bed. striking the the 1/2" rod with a 3 lb hammer a couple times and the chuck came loose

It's about intertia Jeremy, there is often enough mass in the spindle and resistance in friction along the way to resist a sudden shock loading. It has to be hit sharply.

heres a picture of how i removed the chuck 1 is your spindle lock (make you use something to protect the ways)
2. is the a piece of stock chucked in the lathe ( make sure you remove the 2 chuck retainers)
the green arrow is the direction you want to turn the chuck
Jerry is right you have to strike it sharply
