title: Ruby and Qt4: no `rbuic`
body: <p>when I used to use Qt3, I was only have to design my program interface, then use the "rbuic" command to convert the .ui file into a .rb file, and problem solved ...
  but the thing is, now I'm using Qt4, and there is no such thing like "rbuic", so I'm i suppose to write the whole ruby program to run an interface by my self, if yes, then I'll use the Qt3, at least it less painful.</p>
