[GUI] GUI question

Hello; My name is Gabriel Alix; I am currently an undergrad Computers Science major at Colgate University working with Proffessor Phillip Mulary. I am currently working with a group of other people to build a UI but am finding a lack of good examples to study off of. Would anyone have any references, links, or code that shows the inner workings of UI in Haskell? We are look for anything that will help us designs a good GUI. Any help would be appreciated Thank You ~Gabriel Alix
