Before you do this, consider very carefully whether it really is the Right Thing. You should at least make it a feature that the user switches on and off. — JeremyP, Jul 19 '10 at 07:35

You can change the window's windowLevel (via -setLevel:) to NSFloatingWindowLevel.

[window setLevel:NSFloatingWindowLevel];

Documentation is here: Window_Levels

By "on the top", do you mean you do not want your window to be obscured, even if a different app is active? In that case, one way is to start with the NSPanel template in Interface Builder, check the "Utility" option, and uncheck "Hide on Deactivate".
