I realize this isn't exactly what you were asking to do, but perhaps you
should look at the manpage for XCirculateSubwindows.
XCirculateSubwindowsDown will lower your top window to the bottom and
the one below it will be on top. This is very similar to what you
wanted to do and doesn't require you to parse the window tree.
Keep in mind though, for some users, the topmost window is not always
the one that has focus (this is even true of win32 programming when
focus follows pointer (or win32 XMouse) is set), and you must
specifically set input focus to the window. Also some users detest
it (read as "I hate it") when window stacking order is changed on them
by applications.
