It depends on your toolkit. If you're not using any particular toolkit,
the easiest way is to set _NET_WM_WINDOW_OPACITY on your window. See
http://webcvs.freedesktop.org/xapps/transset/transSet.c?view=markup for
an example.

Make sure a composite manager is running (many desktops run one by
default these days).
