Passing an object referance(button) to another class

Hi,
I have 2 classes Class A and Class B ,
 Class A extends JFrame and i have a button "ok" in class A , when i click this button i will create the instance of the class B which is also a Jframe class and i disable the button "ok".

the same way when i click cancel button in Class B, the button "ok" in class A should be enabled.

here is the code:
public class A extends JFrame
{

JButton ok;
public Accounts()
      {
                Container con=getContentPane();
                ok=new JButton("Ok");
                con.add(ok);
      ok.addActionListener(new ActionListener()
            {
      public void actionPerformed(ActionEvent ae)
            {
                              
            ok.setEnabled(false);
            A webfilter=new A();
            webfilter.setVisible(true);
            webfilter.setSize(400,350);
            webfilter.pack();
            }
      });
      }
}

public class B extends JFrame
{
      
public B()
      {
             Container con=getContentPane();
             JButton cancel=new JButton("Cancel");
              con.add( cancel);
 //when i click this button cancel the buton "ok" in Class A should be enabled
       cancel.addActionListener(new ActionListener()
            {
            public void actionPerformed(ActionEvent ae)
                  {
                  dispose();
                               
                  }
            });
           }
