Maybe use the gtk.Container.get_children() call

The pseudo code might look something like this:

Code:

window.changePango(window)

def changePango (self, child):
    if child is a container:
        for subChild in child.get_children():
            changePango (subChild)
    else:
        change the child's pango context

If a child doesn't make a copy, just change the toplevel window's pango context and then maybe call the toplevel window's check_resize().

Check gtk.Container for more info.
