Drawing a Rectangle that never dissapears

Question

I have to draw a transparent square, that never disappears from the user's interface, by clicking to other windows the rectangle remains, only the windows/application content has to be shown behind. I have thought of doing it with OpenGl or Flex or Canvas , but the problem is whenever I click on another window the programmed rectangle disappears .The rectangle has to act as a default image but has to be always at the foreground.

Do I have to mess with the operating system(Linux, Mac or Windows), by creating this image as default?

here is one example http://i42.tinypic.com/15g3vxh.png

You can do that with Java pretty easy. See this link for code examples. If you got your transparent Image, you can use the setAlwaysOnTop(true); Method on the Object, and you are good to go. The only things that could get in front of that are other Applications that are using that method.
