That is a dialog.

Event: Elapsed time = 0.1 seconds
Actions:Clear Dialog1
Create dialog button for dialog 1 called (hero 1)
Set [hero1] equal to last created dialog button
Create dialog button for dialog 2 called (hero 2)
Set [hero2] equal to last created dialog button
Show Dialog1 for player 1 (red)
Event - Dialog is clicked
Conditions - Clicked dialog equal to [hero2]
Actions - Create one [hero2] for player red at position XXX

That's roughly the triggers you need. You'll also have to create variables for each dialog button, and each dialog.
