Splitting a frame on command?

Hi,

I'm trying to build a program that splits a frame into two upon
invocation of a command but I don't seem to be getting anywhere.

I've attached a very minimal test program that hopefully demonstrates
what I'm trying to accomplish. When you push the "Do Split" button,
I'm hoping that two text boxes show up with the splitter in between
them. However, I cannot seem to get the window to split.

Any help would be appreciated!

Thanks,
Devin
