What is the exact reason for needing this?

Why would it? Applications that have window(s) open on the X11 display
that runs a GNOME desktop need not be written using GTK+ at all, even
less need such apps be using GNOME libraries, or have anything to do
with DBUS. They might be running on another machine, running a
completely different operating system like OpenVMS even.

In general, I think the only way to do what you want would be to hack
the X11 server's code to provice the information you need, or snoop on
the communication channels between the X11 server and its clients
