You'll pretty much need to reformat and reinstall to do that. You have to change partitions and format things and that sort of thing. Partition Magic and I'm sure there are other apps out there, will let you shrink and grow partitions and other fancy stuff, but the easiest way would be to start from scratch.

One thing to remember is to actually make both your OS and Apps partitions quite a bit bigger than you'd expect. Windows keeps copies of it's updates and the backout info which can be more than a gig after a while. Also, the temp files grows and can also be more than a gig.

Apps, you think, "this will be more than enough room," but things change, and if a couple of gigs seems like more than enough now, it'll be insufficient later. Better to make it plenty big.
