Я знаю, что вы решили свою проблему с помощью комбинации JPanels, размещенной в BorderLayout менеджере раскладок. Если это работает, это нормально.
Для тех, кому интересно использовать GridBagLayout в качестве решения, я представляю этот класс в качестве примера. Просто скопируйте, вставьте, скомпилируйте и запустите. Перетащите угол окна этого маленького приложения, чтобы увидеть эффекты изменения размера окна.
// Example code showing the flexibility of GridBagLayout.
// Source code generated by WindowBuilder 1.0.0r37 in Eclipse (Indigo Release) on Mac OS X 10.6.7.

// This source code may be used freely forever by anyone taking full responsibility for doing so.
// Each layout manager bundled in Java is quite different from the others. They all have strengths and weaknesses,
// each designed for different purposes and effects.
// GridBagLayout is the most powerful and flexible, but takes some patient practice to understand.
// Funny animated video commentary by a GridBagLayout programmer: http://madbean.com/anim/totallygridbag/
// Hand-coding GridBagLayout is certainly tedious, and nearly impossible for complex forms. So I recommend the use of
// a visual GUI builder such as WindowBuilder in Eclipse, JFormDesigner from FormDev.com, or Matisse in NetBeans.
// Key ideas, "grow" & "fill":
// • In WindowBuilder's Design View, select a widget, then use the "Horizontal grow" and "Vertical grow" icons found in the upper right tool bar.
// • Use the widget's (label's, button's) "Constraints" > "fill" property in the property sheet of WindowBuilder.
// Further ideas:
// • To contain multiple widgets in each area, use JPanel objects where I have used single JLabel and JButton objects.
// Nesting JPanels inside JPanels (or in the JFrame's contentPane) is considered normal in Swing. Each JPanel has its own layout manager.
// • If need be, you can set the Minimum, Maximum, and/or Preferred size of a widget or JPanel.
// • If you want certain widgets or JPanels to get disproportionately more or less of the space gained or lost when a window is resized,
// use "weightx" and "weighty" properties.
// WindowBuilder Tips:
// • If it's your first time: Open the .java file, then click the "Design" button at bottom to see visual editor.
// • Click the "Show Advanced properties" icon at top of a widget's property sheet to see many hidden properties.
