Here's the Swing example from the JRuby download:

    require 'java'

    module Swing
      include_package "javax.swing"
    end

    frame = Swing::JFrame.new("Hello Swing")
    label = Swing::JLabel.new("Hello World")

    frame.getContentPane().add(label)
    frame.setDefaultCloseOperation(Swing::JFrame::EXIT_ON_CLOSE)
    frame.pack();
    frame.setVisible(true);


Cheers
