Java GUI

If I see one more tutorial about building GUIs using netbeans or some other stupida** drag-and-drop visual GUI builder, I am going to f**king off myself. Like, all they do is create ridiculously long walls of unreadable and unmaintainable code... Anyone know how to *actually code* a GUI using pure Java. Preferably Swing. Yes, I know it's old, but the way Swing works just clicks so much more than FX for me. I've looked at the Swing documentation, but either it doesn't answer my questions, or I just haven't looked in the right place :(
