You gave only two choices :)

Difficult to tell. I think ruby-gtk has a slight advantage in this 
regard over FXRuby.

>   * Which one is easier?

Cant really say. My personal feeling is that FXRuby is easier because 
Gtk/gnome really is somewhat large. But then again, both are rather easy 
once you understood how signals work.

That is somewhat impossible to answer. :/

In general I think it is better to just work and not bother which one is 
more "rubyish". Both are actively maintained, it does not so much matter 
which one you use IMHO.
