Dialog box for entering name?

So I'm making a game for the Casual Game market, and a common feature is to have the player enter his/her name into a dialog box. So:

- Should I "roll my own" by displaying a sprite with some sort of text input object in it, and my own OK button? Or should I use Torque's built-in GUI dialog box code? If I use the built-in dialog, is it easy to replace the default graphics with my own? (I want the dialog box's visual appearance to match the rest of my game.)

If the latter, is there a place someone could refer me to that documents how to do this? (How to create a dialog box where you can enter your name, and *especially* how to use my own custom artwork.) I remember the last time I looked into doing GUI work with Torque, it was severely lacking in the documentation area... only one or two brief tutorials that didn't cover what I wanted to do...

BTW, is there some sort of text input object that I could display in any context, which allows the user to click inside it and type in text? Could be useful for things like a High Score page, where you enter your name directly in the line where it will end up...
