Ok, so I was following this tutorial and I noticed it said:

public class TabbedPane extends JFrame

I'm working on my project in NetBeans. When I created my project NetBeans automatically wrote the beginning and ending of my class for me. Here is what it wrote:

public class GWAToolboxApp extends SingleFrameApplication

Do I need to put anything in my code for the JFrame extension?

Don't have netbeans involved with your GUI. Just create your own empty class and extend JFrame

To clarify, NetBeans is a fine IDE so long as you aren't using the Visual GUI Builder.

Honestly, I have no idea what specifically is going on in your code. Why extend the SingleFrameApplication class? What is going on?

Ok, I deleted my project and started it over again. I didn't touch the GUI creator and created a new class file and all it gives me is:

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
package gwatoolbox;

/**
 *
 * @author Tyler
 */
public class GWAToolbox {
    
}

So I guess I'm good to go now.
