[Haskell-cafe] Wire GUI

[Andrew Coppin]

I'm looking at a project which involves a GUI where you can insert 
components and wire up connections between them. Obviously the details 
of what the components are and what code gets executed for them is 
domain-specific, however the general idea of graphically wiring things 
together is quite generic. Has anybody already put together a Haskell 
library for doing this kind of thing?
