Magic 8 Ball

# [Project] Magic 8 Ball
# I'm sure you've used a magic 8 ball at one point in your life. You ask it a
# question, turn it right side up and it gives an answer by way of a floating
# die with responses written on it. You can create one in python. You must:
#   1. Allow the user to enter their question
#   2. Display an in progress message( i.e. "thinking")
#   3. Create 20 responses, and show a random response
#   4. Allow the user to ask another question or quit
#
# Bonus Using whatever module you like, add a gui. Your gui must have:
#   1. A box for users to enter the question
#   2. At least 4 buttons: Ask , clear(the text box), play again and
#      quit(this must close the window)
