I think Xpadder might cost money, or have a trial. Antimicro is opensource, so you could try that first.

I think the interface should be pretty easy to figure out. If you can't find out or nothing on google, I could get my gamepad and see if I can get it to work.
I remember me and Faden had some gamepad force fights. He was pretty good with it, actually! Obviously you can't have the control you'd have with a mouse, though.
