Boarderless Window - win8 style?

Hello all,
Can anyone suggest a way to make a boarderless window? Currently, I am using a floating window to place over top of a main window. This is positionable, but always stays above the main window - sort of simulating a Z axis. The problem is, I do not want any of the boarder showing - so that is does not look like it really is, a window over top of another…

Ideas anyone?

Thanks,
Tim

Entirely borderless windows may be possible through API calls. If what you mean is a full screen effect, like Windows 8 “Metro” or “RT” applications do, you may find what you need at
