Hello,

Yes, you can. Take a look at these sites:

http://developer.kde.org/language-bindings/ruby/index.html
http://korundum.rubyforge.org

(some interesting discussions in the forums in Korundum's site).

You will also be interested in the "Rapid GUI Development with RubyQt"  
ebook by Caleb Tennis:

Do not forget Richard Dale's blog, he is the main author of QtRuby:
http://www.kdedevelopers.org/blog/89

On the other hand, some of us hang around #qtruby and #kde-ruby in Freenode.
