GUIs are hard, in any language.

I am looking for solutions on a Haskell list, because I think chances of 
finding them here are higher than elsewhere.

text field lengths or numeric field ranges, in such a library, for a start?

You are totally right here. I should have said I meant Web UIs, mostly 
interactive forms.
