ActionPerformed not working ??

Question

Hi all, I have written this program to display a box for user to enter a value and display the computed value :-
import java.awt.*;
import javax.swing.*;
import java.text.*;
import java.awt.event.*;
public class ConvertMachine extends JFrame implements ActionListener
//class and instance variable declaration;
public static void main(String[] args)
new ConvertMachine();
public MetricMachine()
// Layout statements
ButtonToLeft.addActionListener(this);
ButtonToRight.addActionListener(this);
} //ConvertMachine statement
public void actionPerformed(ActionEvent evt)
if ( evt.getSource() == ButtonToLeft )
CmNumber = InchesNumber * 2.54;
nameField.setText("CM =" + CmNumber);
else if ( evt.getSource() == ButtonToRight )
InchesNumber = CmNumber / 2.54;
     nameField.setText("Inches =" + InchesNumber);
After I've complied , I set a breakpoint at
" ButtonToLeft.addActionListener(this) ". When I run the program and hit the breakpoint , it proceeds to the next statement and return to
" new ConvertMachine(); " and exit.
I could not understand why the ActionListener did not call the actionPerfomed fuinction.
Can anyone assist me?
Thanks

Sorry for all the trouble. Here is the code :-
import java.awt.*;
import javax.swing.*;
import java.text.*;
import java.awt.event.*;
public class ConvertMachine extends JFrame implements ActionListener
JPanel panel = (JPanel)this.getContentPane();
JPanel panel1 = new JPanel();
JButton ButtonToLeft = new JButton("<");
JButton ButtonToRight = new JButton(">");
GridBagLayout gridlayout = new GridBagLayout();
GridBagConstraints constraints = new GridBagConstraints();
JTextArea cmTextBox = new JTextArea();
JTextArea InchesTextBox = new JTextArea();
double CmNumber = 0.0;
double InchesNumber = 0.0;
public ConvertMachine()
