looking for help

I am disabled and am starting to have problems with my left hand making moving game characters around troublesome.
So I was wondering if its possible to make a psp thumbstick http://www.amazon.com/gp/product/B006UP ... e=&seller= work as wasd on my little 4x9 keyboard or just make it work as a stand alone type thing for moving characters on pc games.

Thanks.
