I think you should talk with Richard Dale and help the qt-ruby project.

Scripting languages qt/kde bindings are based on perl smoke library,
this leads to some problems and limitations.

The best, but expensive, aptitude should be to write a c ext code to 
interface qt lib.


You can ask also help to trolltech, i suppose they are interested.
