That would only give you the apps running in the current X11 session and
you'll probably have to do it for each WM.

No there's not.

Well, I guess you could start by checking out the X11 API, there are
ways of iterating over all windows and also for checking the pid of the
corresponding process. (IIRC it was something like NET_WM_PID).

Anyway, all of that is better asked in a X11 mailinglist/forum.
