You're right, this is absolutely the wrong thing to do!  Not only is it
unlikely to work with many window managers, it's also illegal.  Section
4.1.9 of the ICCCM, "Icons," says:

    Convention: The icon window should be an InputOutput child of the root.

In general, there's no way to prevent the window manager from giving one
of your windows an icon.  That's up to the window manager.  However,
setting the WM_TRANSIENT_FOR hint might do what you want.
