[Haskell-cafe] GUI

I know this question is probably going over old ground - so I apologise in advance. However, I want to know if there has been any practical standardisation in the GUI area. Last time I looked at this it seemed some decisions had been made (bind to existing api - wxWindows?). I am waiting for some real standardisation and a mature API before I jump ship from Java for my day-to-day programming. Has there been any progress? Matt
