Designing your user interface
To design a window, click a designable file (such as WelcomeFrame.java), then
click the Design tab that appears at the bottom of the AppBrowser.
To add a component to your application, click a component on the Component Palette,
then drop it where you want your component to appear in your user interface.
Set the control's properties and events by double-clicking in the Inspector.
