There are a few bugs in the program when I tried to run it:
txt references both the data entry box and the scrolling list box.
you have both bg="black" and fg="black" in your labels so it becomes just a black rectangle.
your bottom button doesn't fit in the frame.
Other than that, this is a great idea!
