How to create a PQ4 style text box?

I was just wondering how you would go about creating a text box that would change size according to how much text is displayed and also so you can put it anywhere on the screen.  I am guessing you would make some sort of interface gui for this command.  I am just not sure how to go about it.  For anyone that needs an example here is one below:

DisplayAt plus a custom textbox GUI should do the trick.

Isn't that a blocking command though, I would want to keep the animations going while the box appeared.
