Which is better for developing GUI applications with Haskell, wxWidgets (via wxHaskell) or GTK (via Gtk2HS)? What are the pros and cons of each? Does it vary depending on which platform you are targeting (I would primarily be working on OS X but would like my programs to work on Linux and Windows too)? ...
