I want to create a very simple window manager for Ubuntu using Ruby. Where should I start? I am somewhat familiar with Qt (from when I used to use C++), but I don't mind using other frameworks.
There's this great presentation, presenting several toolkit alternatives. It's in Portuguese, but it should not be hard to understand the toolkit names and screnshots :)
