After talking to people and reading various posts and articles I reached a conclusion that I have to choose between Tk and GTK2. Tk+Ruby seems to have more resources on the web but GTK2+Ruby looks better and apparently is more easily customizable (custom drawn widgets was easier to create). I've personally chosen GTK2. Check this out: http://ruby-gnome2.sourceforge.jp/hiki.cgi Regarding a good interface builder I have much less experience. I code the interface definitions myself. FireAphis
