You can use the setBounds() of the components you want to place on your form. Like this:
public class Test extends JFrame
     JButton    button1 = new JButton("1");
     JButton    button2 = new JButton("2");
     JButton    button3 = new JButton("3");
     JTextField text1   = new JTextField();
     JTextField text2   = new JTextField();
     JTextField text3   = new JTextField();
     public void Test()
         Container contentPane = getContentPane();
            contentPane.setLayout(null);
            button1.setBounds(252,25,85,26); //x,y,width,height
         button2.setBounds(252,55,85,26);
         button3.setBounds(252,85,85,26);
         text1.setBounds(60,25,168,24);
         text2.setBounds(60,55,168,24);
         text3.setBounds(60,85,168,24);
         contentPane.add(button1);
         contentPane.add(button2);
         contentPane.add(button3);     
         contentPane.add(text1);
         contentPane.add(text2);          
         contentPane.add(text3);          
            setVisible(true);
            setSize(400,300);
       public static void main(String args[])
            new Test();
}
