you'll need a GUI application for Ruby.
There are many ...  see here: http://www.trug.ca/Ruby_GUI_Toolkits
In addition to the list given there, there are some that use Java via JRuby ..
make a Google search for Monkeybars, Profligacy, Cheri.

I like Shoes most at the moment:

you get some example code for your problem right on this page:
