The patch in:

 http://bugzilla.gnome.org/show_bug.cgi?id=568712

abstracts some of the code used for the tray manager into a separate
class, but more work would have to be done to create a true "embed any
widget".

I would not recommend setting the user_data of the root window to a
widget in any circumstance. Outside of the GNOME Shell context, you
could use gdk_window_add_filter(). 

Inside GNOME Shell the right way to intercept events is generally to
hook into gnome_shell_plugin_xevent_filter().
