If I had more time working on this I wouldn't mind rewriting the basic
widgets because reuseing or wrapping existing ones would limit a lot the
design we aim for. Qt's QSpinBox only accepts integer types QListBox can
only display simple labels. I don't know about WxWindows but new styles
(Windows 200x) would take time for another LGPL group to implement. MFC is
limited to Windows.

I agree that some deterministic automata is missing also and Direct X /
OpenGL support is interesting also.
