Trying to make TextBox act like a Console.ReadLine

Question

I want to make a text display on a textbox according to what I type in another textbox after I press a button. I am trying to get this to happen on one Main Form several times having the thread stop at each question and then resume after the button is pressed stopping for the next question.I was thinking of using a Thread.Sleep() method but am getting confused pretty quickly being new at programming.
