There is nothing very convenient for this but you can do it using the
same API as the window manager (hildon-desktop) uses: XQueryTree and
reading some window properties with XGetWindowProperty.  You could get a
some kind of list by taking top-level (== parent is the root window)
windows that have _NET_WM_WINDOW_TYPE property set to
_NET_WM_WINDOW_TYPE_NORMAL.

I'm attaching the source code of a small utility that uses XQueryTree,
you could use it as a starting point.
