Both the parent and child window are just windows, so you can use any of 
the functions for a wxWindow.
So, in the child's on_initialize(), you can do something like:

   self.Centre()
which will centre the child window over its parent.

Or you can do
        self.parent = self.GetParent()
        bx,by, dx, dy = self.parent.GetRect()
        self.Move( (bx, by+dy) )
to move the origin of the child to the bottom left of the parent.

Or .... lots of things like that.

In the parent window, you can add something like

        self.childWindow = model.childWindow(self, MyChild)

and have handlers

of course, you ought to check that the child window exists, etc. :-)
