What I want to do is create two controls full of numbers.
The bottom control is sorted ascending and the smallest number appears on top like a normal wxListbox control.
However the top control is sorted ascending too but the smallest number appear on the bottom of that control.
For the life of me I can't think of a way to implement this on a control that changes size with the window.
Maybe a pic will explain better:

What I'm trying to recreate is the blue and green section.
Anyone know how I can do that? Or how do I go about hacking something like that together?
