Ok,
to set up the windows always on top you need to use one winapi function: SetWindowPos, with of course, required parameters, and so.
To set it always on top use this:

SetWindowPos(myHandle, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE)

Where:
myHandle - is window HWND - handle to the window we want to set up...
HWND_TOPMOST - place the window in the TOPMOST state...
the zeors are the new size and position of the window (we don't want to change it, but only set it on top)
SWP_NOMOVE - will not move the window
SWP_NOSIZE - will not resize the window after change...
and that's all,
if you want to unset the window just call the function again:

SetWindowPos(myHandle, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE);

and i think this is all you need to set/unset the window always on top
