How to make a multicomponent Swing Class in Java

So I am trying to make multiple JLabels inside a JPanel then add it to a JFrame, I am using the construction to set the text of the JLabels (16 of them) but the text is not being set. Why is this? Thanks :)

package GUI;

import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;

import javax.swing.JFrame;

public class Window extends JFrame {
    /**
     * Create the frame.
     */
    GridBagConstraints layout = new GridBagConstraints();

    public Window() 
    {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 450, 300);
        setLayout(new GridBagLayout());

        InfoPane stats = new InfoPane();
        layout.gridx = 0;
        layout.gridy = 0;
        layout.ipadx = 50;
        add(stats.InfoPaneBox("John", "100", "UNSP", "Ukraine", "9\" Knife", "05", "£123", "18"), layout);

        setVisible(true);
    }
}

Here is the multi-component jpanel that i want to add to the JFrame. Also What is the best way to go around making customised components in Classes and then to add them to a main JFrame?

package GUI;
import java.awt.Dimension;
import javax.swing.BorderFactory;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.border.TitledBorder;



public class InfoPane
{

    JPanel container = new JPanel();

    JLabel one = new JLabel("Name:");
    JLabel two = new JLabel("Health:");
    JLabel three = new JLabel("Gang:");
    JLabel four = new JLabel("Location:");
    JLabel five = new JLabel("Weapon:");
    JLabel six = new JLabel("Police Noriety:");
    JLabel seven = new JLabel("Money:");
    JLabel eight = new JLabel("Gang Noriety:");

    JLabel nameJL = new JLabel();
    JLabel healthJL = new JLabel();
    JLabel gangJL = new JLabel();
    JLabel locationJL = new JLabel();
    JLabel weaponJL = new JLabel();
    JLabel policeNorietyJL = new JLabel();
    JLabel moneyJL = new JLabel();
    JLabel gangNorietyJL = new JLabel();


    public JPanel InfoPaneBox(String name, String health, String gang, String location, String weapon, String police, String money, String gangn)
    {
        nameJL.setText(name);
        healthJL.setText(health);
        gangJL.setText(gang);
        locationJL.setText(location);
        weaponJL.setText(weapon);
        policeNorietyJL.setText(police);
        moneyJL.setText(money);
        gangNorietyJL.setText(gangn);

        container.add(one);
        container.add(two);
        container.add(three);
        container.add(four);
        container.add(five);
        container.add(six);
        container.add(seven);
        container.add(eight);
        container.add(nameJL);
        container.add(healthJL);
        container.add(gangJL);
        container.add(locationJL);
        container.add(weaponJL);
        container.add(policeNorietyJL);
        container.add(moneyJL);
        container.add(gangNorietyJL);
        one.setBorder(BorderFactory.createTitledBorder(BorderFactory.createLoweredSoftBevelBorder(), "Stats", TitledBorder.LEFT, TitledBorder.TOP));    
        one.setPreferredSize(new Dimension(150,400));

        return container;
    }
}
