Trying to figure out how easy it is to use ruby to write a desktop application.  It would be nice to have something cross-platform.  At the moment I’m playing with qt4, gtk2, and wxwidgets.

To install Qt4:

• sudo apt-get install libqt4-dev cmake
• sudo gem install qtbindings
• alternatively for ruby 1.8: sudo apt-get install libqt4-ruby
• memory used by “hello world” 94MB

To install Gtk2:

• sudo apt-get install libwxgtk2.8-dev
• sudo gem install gtk2
• alternatively for ruby 1.8: sudo apt-get install libgtk2-ruby
• size of gtk2.so – 3,450,759 bytes
• memory used by “hello world” 66MB
