I appreciate your effort here.
I wanted to say, if you have gone this far with developing a GUI with png's I see no reason to use guictrls at all. You make reference in your code to doing this.
You can draw whatever you need right on the png.
My below modifications adds text to one of the pngs.
As an aside, you have included grey.gif in your zip file, I don't think it is needed.
