             Optional<ButtonType> result=cn.showAndWait();
             if(result.get()==ButtonType.OK){
                 System.out.println("ok button clicked:"+result.get());
                k=0;
             } else{
                 System.out.println("cancel clicked");
                k=1;
             }
            return (scene);
        }

    });

I'm not sure to understand what you really want to do. Do you absolutely need a JavaFX alert in a swing application? JDialog works very well, and Alert and Dialogs works very well too in a JavaFX context.

Have you tried to set your Alert application modal with cn.initModality(Modality.APPLICATION_MODAL) ?

Maybe you can find you answer in this post : How to make a JFrame Modal in Swing java

This is the suggested code in the post:

final JDialog frame = new JDialog(parentFrame, frameTitle, true);
frame.getContentPane().add(panel);
frame.pack();
frame.setVisible(true);

I would create a new JDialog and set as parameter your main frame (parentFrame) and add your JFXPanel to its content.

frame.getContentPane.add(fxPanel)

You can use fxPanel.setScene(yourScene) to add FX content to your JDialog.

Example for the suggestion:

public class Main  {

public static void main(String[] args) {

    // create parent
    JFrame parent = new JFrame("MainFrame");
    parent.setSize(500, 500);

    // center of screen
    Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
    parent.setLocation(dim.width/2-parent.getSize().width/2, dim.height/2-parent.getSize().height/2);
    parent.setVisible(true);

    createDialog(parent);

}

private static void createDialog(JFrame parent) {

    // create dialogs JFX content
    BorderPane layout = new BorderPane();
    layout.setTop(new Button("HELLO"));
    layout.setBottom(new Button("IT'S ME"));
    Scene scene = new Scene(layout);
    JFXPanel dlgContent = new JFXPanel();
    dlgContent.setScene(scene);
    dlgContent.setPreferredSize(new Dimension(200, 200));
    dlgContent.setVisible(true);

    // create dialog and set content
    JDialog dlg = new JDialog(parent, "Dialog", true);
    dlg.setLocationRelativeTo(parent);
    dlg.getContentPane().add(dlgContent);
    dlg.pack();
    dlg.setVisible(true);

}

}

Hope I could help you.
