There is no default "custom dialog box". Unfoirtunately I don't know if there's a module that does that.
But it's not too hard; you can use slasher's methid, or you can create a custom gui to display the text, etc. Just make sure you replace the default "Say" method with your own -- that I'm sure you'll find forum posts that deal with this topic.
