Hi Michael -
I'm also new to Haskell. Although I can't really give a definitive
answer as to whether Haskell is appropriate for GUIs, I can mention
several GUI libraries that exist for Haskell. They are wxHaskell,
Gtk2Hs and qtHaskell.
The following page mentions those and a number of others -
Note - that page says that "there is no standard (GUI lib) and all are
more or less incomplete." Don't be too put off by that - from what I've
seen, although I haven't used them myself, both wxHaskell and Gtk2HS now
seem to be quite complete. I can't really comment on qtHaskell as I
haven't seen that in action.
- Hope this helps....
