In Python:

Create a tkinter GUI application that has two buttons on it. The first button should have in red text the word "Red" on it and the second button should have in blue text the word "Blue" on it. When the red button is clicked you should change the background color of the application window to red and when the blue button is pressed you should change the background color of the application window to blue.

You should place your buttons on the window using the grid manager.
