Well hmm. Honestly consider that by the time you buy all the required parts and learn how to do it you may just be better off buying a PS3 SE stick.
You can use this:
Toodles ChimpSMD
You will also need a common ground board from a xbox 360 controller.
By the time your done you will ahve spent about the same money as a PS3 fight stick. You may be able to find one on sale. I bought one on sale from wallmart for like $15 last fall.
