Write an application that creates a substitution code. You will need a text area in the center of the screen that cannot be edited. The text area will display the code, using a format like A->C, B->Q, C->F, . . . . This means that A would be replaced by C, B would be replaced by Q, C would be replaced by F, and so on. The code will be generated one letter at a time, starting with A and ending with Z. You will have 26 buttons, each labeled with a letter of the alphabet. The first button pressed indicates the letter to be substituted for A, the second button pressed indicates the letter to be substituted for B, and so forth. For example, to create the previous substitution code, you would press the buttons C, Q, F, and so on. As each button is pressed, add the code to the text area and make
