Write a program in any language, so long as it has GUI support for a window system (cannot be text-consoles, etc., and must be a GUI/toolkit/window).

The program must say hello world in any manner (splash image, menu bar, status bar, title, video, message box, other widget stuff, etc.), **so long as a GUI-compliant window appears and shows this text for three seconds**. The person who can code this in the least amount of code used, **including** [NBSP][1]s counted, will take the cake.
