Write a GUI class PayRoll() that calculates the weekly pay given the hours worked and the pay rate. Hours worked over 40 hours per week are given time and a half. For example, 32 hours at $5/hr is $160.00 for the week. While, 50 hours at $20.00/hr yields $1,100.00 for the week.

Your GUI should have:

• two labels and two entry boxes for the user to enter the information
• a Button Compute Weeks Pay that, when clicked, computes the weeks paycheck and displays the amount in a third entry box
  • The entry box that displays the weeks pay should display correctly, with a $ and two digits after the decimal.
• a Button Clear that clears the entries
• check for incorrect input (with a try and except)
  • display this error message (for incorrect input) in a separate window: Uh-Oh, Invalid input
