   private TextField text1;
   
   public Exer5()
   	
   	{
       marky = new Frame ("Simple Calculator");
       text1 = new TextField ("               ");
       buttbsp = new Button (" Backspace ");
       buttc = new Button ("  C  ");
       buttper = new Button ("  . ");
       butt0 = new Button (" 0 ");

 	   buttequal = new Button (" = ");
    } 
   
   public void launchFrame()
   	
   	{
       	marky.setLayout(new FlowLayout());
       	
       	marky.add(text1);
       	marky.add(buttbsp);
       	marky.add(buttc);
       	marky.add(butt7);
        marky.add(butt8);
        marky.add(butt9);
        marky.add(buttdivide);
        marky.add(butt4);
        marky.add(butt5);
        marky.add(butt6);
        marky.add(buttx);
        marky.add(butt1);
       	marky.add(butt2);
        marky.add(butt3);
        marky.add(buttminus);
       	marky.add(butt0);
        marky.add(buttper);
        marky.add(buttequal);
        marky.add(buttplus);
              
        marky.setSize(150,220);
        marky.setBackground(Color.cyan);
        marky.setVisible(true);             
            
    }
   public static void main(String args[])
   	
   	{
      Exer5 markyFrame = new Exer5();
      markyFrame.launchFrame();
    }
}

Hoping for your positive response. .:)

to 'append' actions to a JButton, you need to add an ActionListener to the button.

for instance:

JButton addButton = new JButton();
addButton.setText("add");
        jButton1.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
               addSomething(evt);
            }
        });

...

private void addSomething(java.awt.event.ActionEvent evt) {
    System.out.println("add whatever you want");
}
