Create the LayoutManager with the width and height of the panel you are adding it to:
this.setLayout(new XYLayout(400,130));
Add the components to the panel with a text string that contains x, y, width and height of where you want the component:
//this.add("xposition, yposition, width, height", component);
this.add("47,55,70,25", aLablel);
this.add("47,35,280,20", aTextField);
this.add("170,55,165,20", aButton);
