QT is *extremely* good. My speed with developing GUI applications in C++ is now on par with my abilities in VB...And I can't think of a tool on earth faster than VB for cranking out quick-n-dirty apps :P
The big problem with all the solutions mentioned (besides Delphi, SharpDevelop etc) is that theytake a LOT of time to develop complex GUI applications with.I looked at Python etc, but it would have taken me 10 times (or more) longer to create Lightning Adminusing something other than Delphi.
