My conclusion was that GLFW-b (on hackage) is the best we have right now. I think we could do even better than the C libraries out there by writing the GLUT/GLFW/etc implementation purely in Haskell. We already have x11 and gtk bindings for the linux support. We have win32 api bindings for windows support. What we are lacking is good low level support for OSX GUI programming. Once we have that it's not too much of a stretch to use cabal to glue it together into a cross platform library. I believe that's the right way to go for the long term. Improving GLFW-b is a good short-term route.
Would it be possible to do it with wx? There would be a much larger potential developer pool, since it's cross-platform. (Not getting away from C libraries, but they're stable).
And just to say it one more time, I can use all the help I can get. There are a lot of yaks to be shaved. My hope is that if we all shave one yak then we'll quickly have the libraries we need to do some serious graphics hacking in Haskell. We already have many good libraries for it, we just need to improve and polish a few key libraries. The momentum is here and a few people have already jumped in. Time to get on board!
Count me as onboard; I'm just not sure which ship I'm on yet. Tom
