Answer 1

import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class Dlg extends JDialog {
    public Dlg(JFrame frame, String str) {
        super(frame, str);
        addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent evt) {
                System.exit(0);
            }
        });
    }

    public static void main(String[] args) {
        try {
            Dlg frame = new Dlg(new JFrame(), "No min max buttons");
            JPanel panel = new JPanel();
            panel.setSize(200, 200);
            JLabel lbl = new JLabel("blah blah");
            panel.add(lbl);
            frame.add(panel);
            frame.setSize(400, 400);
            frame.setVisible(true);
        } catch (IllegalArgumentException e) {
            System.exit(0);
        }
    }
}

Here's a related example using setUndecorated() to disable the frame decorations.

import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import javax.swing.AbstractAction;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class FrameTest implements Runnable {

    public static void main(String[] args) {
        EventQueue.invokeLater(new FrameTest());
    }

    @Override
    public void run() {
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setUndecorated(true);
        JPanel panel = new JPanel();
        panel.add(new JLabel("Stackoverflow!"));
        panel.add(new JButton(new AbstractAction("Close") {
            @Override
            public void actionPerformed(ActionEvent e) {
                System.exit(0);
            }
        }));
        f.add(panel);
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    }
}
