Write a program that allows furniture sales (item and price) to be displayed in a list-box one at a time, and then shows the total commission of the sales (5%) upon request. The user should type each item and price into the text boxes and then click on the Display button. This process can be repeated as many times as desired. At any time, the user should be able to press the Show button to display the total commission of all the sales that were entered. Additionally, as soon as the user clicks on the Display button (to display an item and price just entered) the text boxes for Item and Price should be cleared. For this program, you can assume that the user will enter all the sales and then compute the total commission.
