Make a question and answer window

I am new to Unity. I want to make a random question and answer window, in the window it will have one question. If the write the wrong answer, "Wrong Answer" will appear and will pass the next question. If the write the right answer, "Well done" will appear and will pass the next question. Can anyone give me some ideas ?

I dont want the codes. I just want to know which method i use to know well. Thanks very much.
