What exactly are you wanting ported to PC? The frontend GUI? There are several PC frontends for various emulators, such as RetroArch or EmulationStation.
The 2 you mentioned are not nearly as easy to setup as Snes9xGX.
They also require you to setup an emulator behind the GUI, which are lacking a lot of functions as opposed to Snes9GX and FCEU Ultra GX.
