You create the user interface in a PowerJ form. A form is an application window on which you place buttons, text boxes, and other elements of the user interface.
Any program with a graphical user interface has a main form, which is the first window displayed by the application. When you create an applet or application target, a main form is created for you.
Your application may require additional forms, which you can add by selecting File | New from the menu bar or clicking the corresponding toolbar button.
Construct the user interface by selecting components on the component palette and dropping them onto the form. In the code editor for the class, you write code for component events.
