In this assignment, you will write a program that provides the following features:

The program will provide an interface that includes the following:

A factorial button

A recursion log (the multiline text box on the right of the interface)

The program should perform the following functions:

User can enter an integer from 1 to 10.

When the user clicks the Factorial button, the program should compute and display the integer's factorial.

The recursion log should display a message indicating when each recursive call was made.

The interface should also indicate when the base case is reached, and it should list all values returned.

Save the program as Factional.cpp

Have the factorial part but can't make the code for the list box (multiline text box with scroll bar)
