I don't see any reason why not, though the GUI aspect of
Haskell is as well developed as some other aspects of the

At least as well as any other language.

Whether you can get it done quicker depends on how long it
takes you to "get" functional programming. It's very easy to
understand Haskell just well enough to write C programmes in
it. It takes a significantly greater effort -- and time --
to get into the appropriate state of mind to write real
Haskell programmes.

Haskell is very good for this.
