If you want to use OpenGL, you still need some way to open a window,
get keyboard/mouse events, etc. Some possibilities are:

 - OpenGL+SDL
 - OpenGL+GLUT
 - OpenGL+Gtk2HS
 - OpenGL+Xlib+GLX
 - OpenGL+wxWidgets(??)

So far I have liked the OpenGL+Xlib+GLX solution the best -- in part,
because it has the least number of extra dependencies. Though, it is
also the least portable, and most verbose.

Some of the applications I would like to write would have mostly
non-standard widgets. So building on top of an existing widget set
would add an extra layer of (mostly unused) indirection.

ps. Some (minimal) Haskell GLX bindings and Example.hs can be found at:
