• Each program should present the user an interactive interface developed using Tkinter.
• Each program should fulfill a useful, contextualized purpose.
• If you would like to employ a Python concept that we have not yet covered in class, you are welcome to do so.
• Submit each program as a separate *.py file, via Moodle.
• The project is due on Thursday, November 21, 2013 at 11:55 pm.

While you are welcome to do anything that meets the above requirements, you are encouraged to adapt previous projects that employed text input to have a graphical front-end instead. Here are some examples:

• Create a GUI version of the math tutor. It will display problems one at a time, enabling the user to answer each problem when ready. It will also display a running total of the number of problems correctly and incorrectly answered.
• Create a GUI version of the employee database. The user can add new employees and their salaries, or click a button to look up a particular employee's salary. Other buttons will display average, minimum, and maximum salaries.
• Create a GUI gradebook program. The user can add new students, and can also add grades for each student. A button enables the calculation of a student's final letter grade.
