setlayout when dynamic adding textField

I am adding dynamic JTextField and JLabel in panel1 but I am not able to set the layout of JTextField and JLabel. I need to add JTextfield and JLabel to panel1 and I add panel1 to panel. I need to add JTextFields and JLabels in a Top-Bottom manner and set layout. panel1 and panel are instances of JPanel.

My code :

public class MakeScrollablePanel extends JFrame implements ActionListener
{

    static JButton jButton11,jButton12;
    static JPanel panel,panel1;
    static JTextField jTextFields;
    static JLabel label;
    static JComboBox<String> jComboBox;
    static Dimension dime,dime1,dime2,dime3,dime4,dime5;
    static JScrollPane scroll;
    private GridBagConstraints panelConstraints = new GridBagConstraints();  
    BoxLayout bx=null;//  @jve:decl-index=0:

    int count=1,i=0;

    public MakeScrollablePanel() 
    {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Show(); 

        add(jButton11);
        add(scroll);
        dime=new Dimension(600,550);
        setSize(dime);
        setTitle("Priyank Panel");
        setLayout(new FlowLayout());
        setLocationRelativeTo(null);
        setVisible(true);
        setResizable(true);

    }
     private void Show()
     {
         jButton11=new JButton("Add Designation");
         panel=new JPanel(); 
         bx=new BoxLayout(panel,BoxLayout.Y_AXIS);

         scroll=new JScrollPane(panel);
         dime1=new Dimension(500,3000);
         dime5=new Dimension(500,450);
         panelConstraints = new GridBagConstraints();
         scroll.setPreferredSize(dime5);
         scroll.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED);
         panel.setLayout(bx);
         panel.add(Box.createHorizontalBox());
         panel.setBorder(LineBorder.createBlackLineBorder());
         panel.setBackground(new Color(204, 230 , 255));
        jButton11.addActionListener(this);

     }
     public void actionPerformed(ActionEvent event) 
        {
            if(event.getSource()==jButton11)
             {
                label=new JLabel("Add Designation "+count  +" :-");
                jTextFields=new JTextField(30);

                panel1=new JPanel();
                panel1.setBackground(new Color(204, 230 , 255));
                panel1.add(label);
                panel1.add(jTextFields); 
                    panel.add(panel1);
                    panel1.revalidate();
                                panel.revalidate();
                     panel.updateUI();
                count++;
                i++;
             }
        }

    public static void main(String[] args)
    {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                new MakeScrollablePanel();

            }
        });

    }

}
