Dear Laura,
I don't think you're going to have much luck doing things that way.
At best, I think you'd have a window that bounced around the screen.
The reason for that is that the location of the upper left of your
window is under the window manager's control (you can use the
geometry() method to request that it be moved). I doubt that you'd
have much success in getting your window manager to move the window
down just as you were shortening your window. I'd suggest that you
consider a couple of alternatives:

You could put the frame with the control buttons near the top of your
window.

You could used a fixed-size frame (perhaps one with scroll bars) above
your control buttons and pack or grid your other frames into it. Pmw
has a scrolled-frame:

You could use a Pmw PanedWidget; it allows you to add and remove sub-widgets
and they can have varying heights:
