MVC architecture - how it can be applied to swings

Question

hi
I have created a program that gets data from an MS access database and displays it in Swings JFrame, with view, next, previous buttions to traverse through records
I want to write my program in the MVC architecture model. Though i have read details about it, i am unable to apply it on new programs.
Any one please help me with an instance of a program or modify the below program to suit the MVC architecture
thank u

class display extends JFrame implements ActionListener
ResultSet rs;
Statement st;
JTextField tf;
JLabel l;
Button b0,b1,b2;

display()throws Exception
tf = new JTextField(10);
l = new JLabel("Empno: ");
b2 = new Button("Previous");
b1 = new Button("Next");
b0 = new Button("View");
connection con = new connection();
Container c = getContentPane();
c.setLayout(new FlowLayout());
setSize(300,300);
c.add(l);
c.add(tf);
c.add(b0);
c.add(b1);
c.add(b2);
