package Main;

import javax.swing.*;

import java.awt.*;
import java.awt.event.*;


public class code extends JFrame{

    public static JTextField consol;
    public static String title = "Metal-Lock:The Start";
    public static Dimension size = new Dimension(650, 550);
    public static JPanel panel;
    public static JButton enter;
    public static JLabel output;

    public static void main(String args[]) {
        code frame = new code();
    }
        public code() {
            setTitle(title);
            setSize(size);
            setResizable(true);
            setLocationRelativeTo(null);
            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            setVisible(true);

        //  VISITOR LIST
            CONSOL();
            P1();
            P2();
}
//******************************************************************************************************************************

        public void CONSOL() {
                consol = new JTextField(30);

                consol.addActionListener(new ActionListener() {
                    public void actionPerformed(ActionEvent e){
                        String input = consol.getText(); 
                        output.setText(input); 
                    }});
                final JButton enter = new JButton("Enter");
                 enter.addActionListener(new ActionListener() {
                    public void actionPerformed(ActionEvent e){
                        String input = consol.getText(); 
                        output.setText(input);
                        panel.add(consol);
                        add(panel);

                        panel.add(enter);
                        add(panel);

                        output = new JLabel();
                        panel.add(output);
                        add(panel);
                    }
                });      
                }

If you are using Eclipse, you could use an UI Editor. For Instance WindowBuilder. After that you can learn from the generated code too. — Gábor Csikós, Nov 23 '13 at 11:03
TY you Gábor Csikós for showing me to the window builder but now I have to make the enter button work so that it will show what I typed in. Hers the like to my new question! http://stackoverflow.com/questions/20169052/press-on-button-equals-print-what-ever-is-on-jtextfiled-on-the-lable — user3024659, Nov 23 '13 at 23:10
unrelated: please learn java naming conventions and stick to them — kleopatra, Dec 02 '13 at 16:11

Just went really quickly through your code.

Change these lines:

GridBagConstraints R = new GridBagConstraints();
R.gridx = 0; R.gridy = 0;    
JLabel grid1 = new JLabel ("Hello");
//important to set these R values BEFORE you ad grid1.
panel.add(grid1, R);

Change this in all lines there...

You are adding 6 Labels all to the location gridx=0 and gridy=0, which is wrong. Imagine it like an excel tabel, you are inserting every label to field 1.

If you want to add fields do it like this

E.g.

x  y 
z

//a.gridx=0; a.gridy=0;
//y.gridx=1; y.gridy=0;
//z.gridx=0; z.gridy=1;

x coordinates are horizontal.
y are vertical starting from the top left corner.

Read this article, it's really good:
