We will build a calculator GUI using JPanels. Please note, it does not work as a calculator just yet, it simply looks like one. Note that in the North region of the frame, if you add the text area directly the frame, it will not look like below but you have to ensure (using JPanels) that your GUI looks exactly as shown. Also, each button carries either the number or an operator symbol instead of text. You will create your own methods for creating Panels and adding them to the JFrame
