If you cant answer this please dont waste my question. thank you.

This cryptographic program run and produce text screen output. You are to create a GUI that uses the program. Your program (GUI) must allow a user to input of a message to be coded. It must also have an area to show the plaintext, the ciphertext, and the decrypted text. If required by your choice of cryptographic method, the user should have an area to input a key. You should also include instructions to the user on what and how to use your program. Remember user-friendly.

You should not have to rewrite any of the example programs just modify them to use a GUI.

Please add comments to code
