"Creating the LookandFeel Application" is a slightly longer tutorial that walks you through the creation of an application that contains a JavaBeans component, radiobuttongroup that you will create. The component is a very simple radio button panel that you will add method calls to using the Connection wizard. When you have completed creating the component, you will add it to the Component Palette. You can then customize the component for future use as you wish.
