I mean JFrame. I want to open popup (modal) JFrame with 3 buttons,
assign the integers 0,1,2 to the buttons and return them to "parent"
JFrame. During this process, main JFrame should be "frozen" (thread
paused) until the response won't come from this "modal popup"

Basically I want to recreate JOptionPane.showConfirmDialog,
using separate JFrame.


Ah OK. Short answer: no you can't do that.

Longer answer: Use a JPanel instead of a JFrame, that'll work. You can
also use JDialog directly or use some of the other methds in JOptionPane
to create different types of JOptionPanes.

There's an example of putting three buttons on a JOptionPane here:

Here's a quick example of popping a JOptionPane over a JFrame I whipped up.

package test;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

public class JOptionPaneTest {
    public static void main(String[] args) {
       SwingUtilities.invokeLater(new Runnable() {
          public void run() {
             final MainView frame = new MainView();

             frame.addButtonActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                   Object[] options = {"Yes, please",
                      "No, thanks",
                      "No eggs, no ham!"};
                   int n = JOptionPane.showOptionDialog(frame,
                           "Would you like some green eggs to go "
                           + "with that ham?",
                           "A Silly Question",
                           JOptionPane.YES_NO_CANCEL_OPTION,
                           JOptionPane.QUESTION_MESSAGE,
                           null,
                           options,
                           options[2]);
                   frame.setResult( Integer.toString( n ) );
                }
             });
             frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
             frame.pack();
             frame.setLocationRelativeTo(null);
             frame.setVisible(true);
          }
       });
    }
}
class MainView extends JFrame {
    private final JLabel resultLabel = new JLabel();
    private final JButton button = new JButton("Click me");
    public MainView() {
       JPanel panel = new JPanel();
       panel.add(resultLabel);
       panel.add(button);
       add(panel);
    }
    public void addButtonActionListener(ActionListener a) {
       button.addActionListener(a);
    }
    public void setResult( String result ) {
       resultLabel.setText(result);
    }
}
