You can plug the guitar controller from PS2 Rock Band into a USB slot on your pc.Whater you can get it to work or not is anybody's guess.
The GH controllers work through the controller ports on the PS2 so you would have to splice the guitar controller with a USB cable to plug it into your pc...assuming you have an extra USB cable and a spare guitar controller to tear up.
I would assume you don't (I have two guitars...the Kramer from Guitar Hero 3 and the Fender Strat that comes with Rock Band and I would not consider either a "spare parts" guitar) so if you have a few extra bucks (Probably less than the GH controller and the cable you destroyed) you can probably pick up a used Rock Band controller and plug it into your pc.
That would be my recommendation.
[hint] Not that this has anything to do with FPSC and it is totally off-topic but as long as you brought it up... [/hint]
