GUI Design

In this homework assignment, you will create a small GUI application using Python. Your application should have the following features:

1. A window with a title of your choice and a custom size.
2. A label that displays a message of your choice.
3. A button that, when clicked, displays a message box with a message of your choice and an input field where the user can enter a response.
4. A second button that, when clicked, displays the user's response in a label on the main window.
5. A button on the main window that saves the response to a text file.

To complete this task, you will need to use the kinter library. The main window is created using the Label and Button classes.

Next, create a function for the first button that will display a message box with an input field using the askstring module from Tkinter. The function should retrieve the user's input from the input field and display it in a label on the main window.

Finally, create a function for the second button that will open a save file dialog using asksaveasfile and save the content of the message label to a text *.txt file.
