Answer 1

From you answer its not very clear what your problem is. A simple, but often sufficent solution is to change the look and feel for you application to the Systems default look an feel (so Swing looks just like a native application). All you need to do is insert the following code somewhere before any of your UI is created/shown (if you don't know where, place it as the first in your main-method):

try {
    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e) {
// exit application, log  or ignore exception
}
