JLabel JTextField JButton ActionListener

Change the RandomWalk program so that it uses the above instead of a
JOptionPane to get its input.
Basically, copy and paste the incantations from the RandomLines
program into the RandomWalk program.

Constrain the "walker" so it doesn't leave the applet area.
Indicate how many steps it takes to return to the starting position.

Slow down the walking by inserting this incantation in the loop in
paint:  it pauses the program for sleepDelay milliseconds.

try {
   Thread.sleep(sleepDelay);
}
catch (InterruptedException e) {
}

Add another GUI textfield widget to input the value of sleepDelay.
