Fullscreen Chromeless Web

I’ve been given the task at work to try and make an office app we use on our local server go full screen, like watching a youtube video in full screen. No browser, purely for display purposes. I don’t think there is a way to do this, but I thought I would ask here first. The only way I can think to do this would be to make an swf that does the same thing with MySQL, or figure out how to turn php into a .exe file.

Any suggestions?
