I mean JFrame. I want to open popup (modal) JFrame with 3 buttons,

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);
}
}
