But have you tried Wt::Ruby which is a 'QtRuby for web apps'? See 
http://github.com/rdale/wtruby/

I haven't done anything to it for a while, but the project isn't dead and I'm 
keen to get it working with Arno's new smoke generator as soon as I have time. 
Maybe it is possible to do something similar to what Declan has done with 
QtRuby and the Rails generators, but with Wt::Ruby instead?
