Need help on moving a drew oval

Question

hey guys,
I'm trying to build a small maze game. The game has 3 by 3 grid (squares) and four buttons (direction). This is what i've done so far, there's more to it but i'm stuck in half way. I've drew an oval at the bottom left corner (the starting psoition) and the goal is to reach at top right corner. So far i've not yet defined which square is wall and which is open. I smply wants to move the oval to new x, y position when the user click on specific direction button (south, north, east, west) but i really don't know how to do it. Please please help me! Thankyou so much =] Here is the code what i've so far:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MyMazeGame implements ActionListener {
    JButton south, east, west, north;
    JPanel main, maze, dir;
    JFrame sFrame;
    JLabel dirL;
    final int MAZE_X = 100, MAZE_Y = 150, MAZE_WIDTH = 80, MAZE_HEIGHT = 80, MIN_X = 120, MAX_X = 282, MIN_Y = 168, MAX_Y = 330, OVAL_WIDTH = 25, OVAL_HEIGHT = 25;
    int newX = 0, newY = 0, moveX =  MIN_X, moveY = MAX_Y;
    Graphics g;
    public MyMazeGame() {
        //Create and set up the different windows(Frames).       
        sFrame = new JFrame("My Maze Game"); 
        sFrame.setSize(new Dimension(70, 20));
        //Create and set up the panel.     
         * draw the grid on the panel
        main = new JPanel() {
            protected void paintComponent(Graphics g) {
                super.paintComponent(g);               
                g.setColor(Color.white);
                for (int r = 0; r < 3; r++) {
                    for (int c = 0; c < 3; c++) {
                        g.fillRect(MAZE_X + newX, MAZE_Y + newY, MAZE_WIDTH, MAZE_HEIGHT);
                        newX += 81;
                    newY += 81;
                    newX = 0;
                g.setColor(Color.black);  
                g.setFont(new Font("Serif", Font.BOLD, 20));
                g.drawString("START", 105, 380);
                g.setColor(Color.red);  
                g.setFont(new Font("Serif", Font.BOLD, 20));
                g.drawString("FINISH", 270, 175);
                drawNewMove (g, moveX, moveY, OVAL_WIDTH, OVAL_HEIGHT);
        dir = new JPanel();
        main.setPreferredSize(new Dimension(500, 500));
        main.setBackground(Color.black);
        //Add the extra component
        addComponents();
        //Add the panel to the window(Frames).
        sFrame.getContentPane().add(main, BorderLayout.WEST);
        //Display the windows.
        sFrame.pack();
        sFrame.setVisible(true);
    } // end 
     * run the program
    public static void main(String args[])  {
        new MyMazeGame();   
     * add the extra components (buttons, labels etc.) on the panel
    public void addComponents() {
        south = new JButton ("SOUTH");
        north = new JButton ("NORTH");
        east = new JButton ("EAST");
        west = new JButton ("WEST");
        dirL = new JLabel("Choose your direction", JLabel.LEFT);
        main.setBorder(BorderFactory.createLineBorder (Color.white, 5));
        south.addActionListener(this);
        north.addActionListener(this);
        east.addActionListener(this);
        west.addActionListener(this);
        dirL.setBackground(Color.black);
        dirL.setForeground(Color.white);
        dirL.setFont(new Font("Serif", Font.BOLD, 15));
        main.add(dirL);
        main.add(south);
        main.add(north);
        main.add(east);
        main.add(west);
     * perform all the action here
     * This method prints out the current x, y location and new x and y location when a button is clicked
    public void actionPerformed(ActionEvent event) { 
        System.out.println("Current y location: " + moveY);
        System.out.println("Current x location: " + moveX);
        if (event.getSource() == south && moveY < MAX_Y) {               
            moveY += 81;
            System.out.println("Moved down: " + moveY);    
        } else if (moveY > MIN_Y && event.getSource() == north) {
            moveY -= 81;
            System.out.println("Moved up: " + moveY);
        } else if (moveX < MAX_X && event.getSource() == east) {
            moveX += 81;
            System.out.println("Moved right: " + moveX);
        } else if (moveX > MIN_X && event.getSource() == west) {
            moveX -= 81;
            System.out.println("Moved left: " + moveX);
        } else
            System.out.println("Invalid move, can't go out of the grid");
     * draw the oval 
    public void drawNewMove (Graphics g, int x, int y, int w, int h) {
        g.setColor(Color.black);
        g.fillOval(x, y, w, h);
}Please someone guide me, thanks a tons.
