There are several approaches.
You should add these components to a container of some kind (try a JPanel). For three items, you can set the layout to BorderLayout and add each one to a different region (there are 5 - North, South, East, West and Center)...
Try something like this:
JPanel panel = new JPanel(new BorderLayout());
panel.add(myTextField1, BorderLayout.NORTH);
panel.add(myCombo, BorderLayout.CENTER);
panel.add(myTextField2, BorderLayout.SOUTH);
Be sure to add the panel to your JFrame with
getContentPane().add(panel);
pack();
show();
Hope this helps...
