I imagine that the menu design would be setup with a combination of pictures, and variable manipulation. I know message-boxes only take four lines of text, and there's no real way around that. At least, to the best of my knowledge. I suppose you could try doing the text placement as pictures? It's certainly not impossible, just immensely annoying.
I don't recall if there is an event-command to alter stats for the stat distribution system. I'm pretty sure you can set up items to increase stats on a permanent basis, but, I imagine that's not quite the thing you're looking for here.
