Add three StatusBar components from the JBCL tab to Panel 4 as shown in the image below. Don't worry about their sizes. Just make sure they are contained by Panel 4. This panel will change to GridLayout later which will make the status bars the same size.

The two properties involved are called bevelInner and bevelOuter. The values possible for these properties are:

Your status bar should look something like this:
