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.
I agree with your approach. Although getting a window on screen really isn't much code, so I'd vote for going straight to a Haskell replacement for GLUT et al.
And just to say it one more time, I can use all the help I can get.
I don't have much time, but if someone started a github project for a Haskell GLUT replacement I could probably chip in here and there. Ta, Sam
