This has in general nothing to do with X11, but depends on the underlying system (on linux, check the /proc filesystem. Do *not* ask such things on lkm - they're gonna eat you)

To monitor the resources an application holds via the X11 server (amount of allocated pixmaps etc.), check the sourcecode of xrestop.

To get several attributes of a random Window (that is *not* the same as a process nor application) check http://tronche.com/gui/x/xlib/window-information/XGetWindowAttributes.html for the xlib API - there's corresponding xcb_get_window_attributes
