A good answer might be:

The two buttons have been defined.

Adding Buttons

A skeleton of a constructor has been added to the program. 

import java.awt.*; 
import java.awt.event.*;

public class TwoButtons extends Frame implements ActionListener
{
  
  Button redButton = new Button("Red");
  Button grnButton = new Button("Green");
  

  TwoButtons()                           // constructor for TwoButtons
  {


  }
  . . . . more code will go here . . . . 

  public static void main ( String[] args )
  {
    TwoButtons demo  = new TwoButtons() ;
    

    . . . . more code will go here . . . . 
    
    demo.setSize( 200, 150 );     
    demo.setVisible( true );      

  }
}

. . . . more code will go here . . . .

Now remember that GUI components need to be add()ed to the container.
