You might want to have a look at Pmw's _centreonscreen method:

    def _centreonscreen(self):
	# Centre the window on the screen.  (Actually halfway across
	# and one third down.)

        parent = self.winfo_parent()
        if type(parent) == types.StringType:
            parent = self._hull._nametowidget(parent)

        # Find size of window.
	self.update_idletasks()
        width = self.winfo_width()
        height = self.winfo_height()
        if width == 1 and height == 1:
            # If the window has not yet been displayed, its size is
            # reported as 1x1, so use requested size.
            width = self.winfo_reqwidth()
            height = self.winfo_reqheight()

        # Place in centre of screen:
	x = (self.winfo_screenwidth() - width) / 2 - parent.winfo_vrootx()
	y = (self.winfo_screenheight() - height) / 3 - parent.winfo_vrooty()
	if x < 0:
	    x = 0
	if y < 0:
	    y = 0
        return '+%d+%d' % (x, y)

If you replace self resp. self._hull with your window and pass the return value to
a call of its geometry() method it should do what you want.

I hope this helps
