I'll assume that you have a JFrame (an application window) to contain your application GUI stuff. In the JFrame, get your content pane and add the components to it using appropriate layout managers:
public class MyAppFrame extends JFrame {
     //-- class members
     JTextField jtf_Text;
     JButton jb_Button;
     JList jl_List;
     MyAppFrame(String title) {
          //-- initialize frame
          super(title);
          setLocation(x,y); //-- enumerate x and y
          setSize(w,h);       //-- enumerate w and h
          //-- add components to frame
          //---- this is the panel into which to place components for the frame
          JPanel contentPane = getContentPane();
          contentPane.setLayout(new BorderLayout());
          //---- label textbox button
          JPanel panel = new JPanel();
          panel.setLayout(new FlowLayout()); //-- fits components, first horizontally, then vertically
          panel.add(new JLabel("Name: "));
          panel.add(jtf_Text = new JTextField(/*Fill in ... */));
          panel.add(jb_Button = new JButton("Button"));
          contentPane.add(panel, BorderLayout.NORTH);
          //---- label
          panel = new JPanel();
          panel.setLayout(new GridLayout(2,1)); //-- 2 rows, 1 column
          panel.add(new JLabel("Label: "));
          panel.add(jl_List = new JList(/*Fill in... */));
          contentPane.add(panel, BorderLayout.CENTER);
          //-- display frame
          setVisible(true);
     public static void main(String[] args) {
          MyAppFrame maf = new MyAppFrame("Application Title");
}Realize that there is no absolute placement control of components, only relative placement precomputed and handled by the layout managers. Therefore, if the JFrame is resized, components may be shifted around depending upon the attributes of the layout manager. This is a good time to look at the Java 2 Swing tutorials or get a good book on Java Swing. "Graphic Java 2: Mastering the JFC, Vol. 2 - Swing" (Sun Microsystems Press) is recommended. Also keep abreast of differences between older Java versions (1.2, 1.3) and the latest (1.4).
