Yes, there is. Google and you can find all sorts of adapters that let you go Playstation->PC, or Playstation->Gamecube, etc.

I think that the playstation controller is horrible and is a very poor design, but I also realize that other people have the exact opposite opinion, so I respect that.

I recently got an adapter that lets me hook up my Gamecube controller to my PC and I'm very happy with it, so if you do the same for your playstation controller, I'm sure you'll be very happy with it.
