At http://www.dcs.gla.ac.uk/~meurig/TclHaskell/

 you will find a link to TclHaskell, which has a GUI and is easy to use.

Here, for example, is a short program which opens up a window:

	let f = do {w <- window []} in start f

and here another, which stores the title for the window in a mutable
variable:

	let f = do {ref <- newState "how to use state";valueOfRef <- readState
ref;w <- window [];title w valueOfRef} in start f


I'd be interested in hearing from anyone who uses TclHaskell.
