After all you should have a working ruby installation with KDE 4 bindings.

So lets try the a very minimalistic KDE 4 application to get a first impression.

Interactive Hello Ruby

Implementation Using Qt 4

require 'Qt4'

a = Qt::Application.new ARGV w = Qt::PushButton.new( "Click me to quit" ) do

 connect( SIGNAL :clicked ) do
   puts "Do something else"
   Qt::Application.instance.quit
 end

end w.show a.exec

require 'Qt4'

a = Qt::Application.new ARGV w = Qt::PushButton.new( "Click me to quit" ) w.connect( SIGNAL :clicked ) do

   puts "Do something else"
   Qt::Application.instance.quit

end w.show a.exec

require 'Qt4'

class Qt::Application

 slots :doSomething

 def doSomething
   puts "Do something else"
   Qt::Application.instance.quit    
 end

end

a = Qt::Application.new ARGV w = Qt::PushButton.new( "Click me to quit" ) w.connect( SIGNAL :clicked, a, SLOT :doSomething) w.show a.exec
