I took a look on to that stuff... And... it looks like a mix of monkey with motorcycle. They are using similar strategy to wxDevCpp, which is going from Borland's idea. But in Borland there is one advantage: it has C++ extantions like properties and pointers on to classes methods, given after published:. gnu gcc doesn't have those features. That is why I can say that wx Developers stacked with limited MS C++ model of GUI development.
