I am hoping that someone on this list can set me straight !!

I have an app (below) that calls a class containing a Swing JFrame. My
understanding is that swing starts its own java thread (which explains the
issue i am seeing).

How do I Call a class (of swing JFrame) to gather information and have the
caller "wait" for a return???? (BTW JDialog will not provide enough
functionality for this app).

You can see my (feable) test attempt below. Where am I off course ???
TIA !
------------------
import javax.swing.JDialog;
public class test_caller {

        public static void main(String[] args) {
                test aWin = new test();
                aWin.show();
                System.out.println("From caller userid="+aWin.userid);
        }
}

import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JTextField;
public class test extends JFrame {
        public String userid;
        private javax.swing.JPanel jContentPane = null;
        private JButton jButton = null;
        private JTextField User = null;
        /**
         * This is the default constructor
         */
        public test() {
                super();
                initialize();
        }
        /**
         * This method initializes this

         */
        private void initialize() {
                this.setName("Main_JFrame");
                this.setSize(300,200);
                this.setContentPane(getJContentPane());
                this.setTitle("Tester");
        }
        /**

                        jContentPane = new javax.swing.JPanel();
                        jContentPane.setLayout(null);
                        jContentPane.add(getJButton(), null);
                        jContentPane.add(getUser(), null);
                }
                return jContentPane;
        }
        /**

                        jButton.setBounds(62, 90, 172, 63);
                        jButton.setText("Do It");
                        jButton.addActionListener(new java.awt.event.ActionListener() {
                                public void actionPerformed(java.awt.event.ActionEvent e) {
                                        System.out.println("actionPerformed()"); // TODO Auto-generated Event stub actionPerformed()
                                        System.out.println("User="+User.getText());
                                        userid = User.getText();
                                        test.this.setVisible(false);
                                        test.this.dispose();
                                        return;
                                }
                        });
                }
                return jButton;
        }
        /**
         * This method initializes jTextField
         *
         * @return javax.swing.JTextField
         */
        private JTextField getUser() {
                if (User == null) {
                        User = new JTextField();
                        User.setBounds(68, 23, 199, 35);
                }
