[Haskell-beginners] gui pkgs

Hi I'm trying to create a calculator in Haskell, something like the one in the enclosed image. To program the gui , I thought i might use a toolkit such as wxHaskell to create the buttons and frame etc.. I followed all the instructions on the wxHaskell homepage and everything seemed to install properly. Next I tried to use it with ghci, but to no avail. It seems you have to register wxHaskell with ghci by using a command like but that crashes . Every tutorial I read didn't work. Does anyone have a clear set of instructions,that does work? Also, is there a better toolkit for doing guis than wxHaskell? I tried Glade, but it's so bug-ridden I couldn't get anything done. I need help.
