Create a calculator application.

The user interface should consist of buttons for the digits 0 through 9, a button for each arithmetic operator, a Clear button

and two label boxes to display the results. One label box should hold the current number and be located at the top of the

form. The other label box should be located to the right of the calculator buttons. As you click each numeric button, the

number is appended to the current number that appears in the label at the top of the form. When you click an arithmetic

operator button, the current number and the operator should be appended to the display in the label at the right of the form

on a new line, followed by the result of the calculation on a new line, and the contents of the current number label box should

be cleared. The application must have a menu system that allows the user to change the font and color of the label boxes,

the "About" dialog box, and gracefully exit the application.
