change the default skin for applications in netbeans

I'm developing a Java application using Netbeans, and I want to change the default skin for the JFrame and buttons ...

I googled about it and I couldn't find anything.

In Visual Studio I was using SkinCrafter.

Is there any program or addon that allows me to change the default skin for applications in Netbeans ?

try {
        // Set System L&F
    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    // or UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel");
    // or UIManager.setLookAndFeel("com.sun.java.swing.plaf.motif.MotifLookAndFeel")
} 
catch (Exception e) {
   // handle exception
}

Oracle site about

for installed skins:

    for( LookAndFeelInfo info : UIManager.getInstalledLookAndFeels() ) {
        System.out.println( info.getName() );
    }
