WxWidgets... a toolkit aiming to make applications look "native" on each supported platform. It has bindings for just about every language. The ruby bindings are called wxruby: http://wxruby.rubyforge.org/wiki/wiki.pl

The bindings are incomplete and the documentation is non-existent at this point. I've spent a lot of time looking at wxRuby.

In that case... Swig. Use any C/C++ library (like WxWidgets) from Ruby. It is a PITA, but it works.

you need a shave and a haircut =)

I look fantastic.
