Velu:

Well, you should either be all JFC or no JFC to start.  So, convert your
class to extend JFrame as a start.  Adjust the add calls to the
appropriate getContentPane().add() calls as needed and try again.

Hint:  Run the Application Wizard and use the JFrame in the Designer to
see the appropriate syntax for getContentPane().add()...
