I don't know if anyone cares. But I've made a quick port of libwiigui for the PC with SDL and OpenGL (should compile in windows and linux with gcc)
It doesn't do sound yet, and I'm only using it to test stuff before I put it on the Wii. And it's slllooowww. But it works, and could save someone some time.
So if anyone wants it, give a shout.
