Java Programming

Please help turn the following command prompt program into an intro level Java GUI program that consists of a single JLabel and JButton.

JLabel will display a welcome message and display random questions and answers when the JButton is pressed.

JButton will begin say Start (this will tell JLabel to display the first question when clicked), change to Answer (this will tell JLabel to display the answer to the current displayed question), and then change to Next Question (this will tell JLabel to display the next question)

After all questions have been answered, the main button should be disabled and a dialog box should ask the user if they want to go through the questions again or not. Yes will restart program and No will exit the program.

The code below runs great in a command prompt, I just need to convert it to a GUI application. The questions are displayed randomly after the user command has been input. If you could comment out my work and add comments to what you added, that would help my development as a programmer immensely.

Thank you for your help! I really appreciate it!
