I haven't done it myself yet, just invesitgating for my own "upcoming" cabinet plans...but from what I hear it isn't hard at all.
I am IN NO WAY inclined to working with this sort of stuff, so I would give you the same advice I gathered when working on anything you're unfamiliar or uncomfortable with....
"Get the proper tools..cheap-out here and increase the stress later!"
Make a trip to your local home improvement store and inquire about the best methodology or maybe someone here can recommend those little bits n' bobs that'll make the application/finishing THAT MUCH EASIER.
