How can I make letters the same width in JLabel?

I am developing a Hangman game and am having some difficulties. The game is not over (yet), I'm just trying to get my layout and frame set up correctly. My problem is when I type the hangman it looks all crooked and inconsistent. When I print the same to the console (with eclipse) and terminal, it works fine (below). In my window, I want it to look like this when all the guesswork is:

   |¯¯¯¯¯|
   |     O
   |    /|\
   |    / \
___|___

      

        
        
        
      

    

It now looks like this:

I used GridLayout

to make the hangman, with JLabels. I tried to align it by adding extra spaces, but it's still a little crooked. Is there a way to make all characters ("|", "/", "¯", "\", "_" and "") occupy the same width? Is there a specific font I can use? Here's my program:

import java.awt.*;
import java.util.Random;
import javax.swing.*;

import mycomponents.TitleLabel;

public class Hangman extends JFrame {
    private static final long serialVersionUID = 1L;
    private GridLayout layout = new GridLayout(5,0);
    private Random rand = new Random();
    private String randWord;
    private int wrongGuesses = 6;
    JLabel top = new JLabel();
    JLabel body1 = new JLabel();
    JLabel body2 = new JLabel();
    JLabel body3 = new JLabel();
    JLabel bottom = new JLabel();

    public Hangman() {
        initGUI();
        setTitle("Hangman");
        pack(); 
        setLocationRelativeTo(null);
        setVisible(true);
        setResizable(true);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
    }

    private void initGUI() {
        //TitleLabel is from a different class which I created
        TitleLabel titleLabel = new TitleLabel("Hangman");
        add(titleLabel, BorderLayout.NORTH);
        Font font = new Font(Font.SANS_SERIF, Font.PLAIN, 20);
        JPanel center = new JPanel();
        center.setLayout(layout);
        center.setSize(200,200);
        add(center, BorderLayout.CENTER);
        top.setText("    |¯¯¯¯¯¯|");
        body1.setText("    |");
        body2.setText("    |");
        body3.setText("    |");
        bottom.setText(" __|__ ");
        top.setFont(font);
        body1.setFont(font);
        body2.setFont(font);
        body3.setFont(font);
        bottom.setFont(font);
        center.add(top);
        center.add(body1);
        center.add(body2);
        center.add(body3);
        center.add(bottom);
        JTextPane guess = new JTextPane();
        add(guess, BorderLayout.SOUTH);
        redraw();
    }

    private void redraw() {
        if (wrongGuesses == 1) {
            top.setText("    |¯¯¯¯¯¯|");
            body1.setText("    |    O");
            body2.setText("    |");
            body3.setText("    |");
            bottom.setText("___|___");
        } else if (wrongGuesses == 2) {
            top.setText("    |¯¯¯¯¯¯|");
            body1.setText("    |    O");
            body2.setText("    |    |");
            body3.setText("    |     ");
            bottom.setText("___|___");
        } else if (wrongGuesses == 3) {
            top.setText("    |¯¯¯¯¯¯|");
            body1.setText("    |    O");

            body2.setText("    |    |");
            body3.setText("    |   / \\");
            bottom.setText("___|___");
        } else if (wrongGuesses == 5) {
