It sounds like you want xwininfo.

If you want to code it yourself, both xwininfo and xprop do this, so you
could look at how they do it.
(It is probably a little harder than you might think, as you probably
want the XID of the "application" window, and not any random subwindow
or the root window or a window created by the window manager...)
