How make Swing app Rotated 90 Deg? i.e. On its side

Question

I want to make my entire swing app (including buttons, JTextArea, etc) rotated 90 deg to the right. I know this sounds weird, but I want to do it for a PDA. I can use swing on a PDA (check on google for swing personal java) and I want to be able to have the screen the long width.
Does anyone know how I can do this?

I can suggest some solution but it has not been proved to work. So just read it and make your own component carefully.
First, subclass the Swing-widget to be rotated and name it RButton or whatever.
Then, draw the content on a new BufferedImage instance and use AffineTransform to draw this BufferedImage onto the original Graphics context. Here is the example code.public class RButton extends javax.swing.JButton {
  public void paintComponent( Graphics g ) {
    // 1. create a new BufferedImage to draw on.
    BufferedImage bi = new BufferedImage( this.getWidth(), this.getHeight(), BufferedImage.TYPE_INT_RGB );
    // 2. draw the content (using JButton's paintComponent())
    super.paintComponent( bi.getGraphics() );
    // 3. save the old transformation matrix
    Graphics2D g2 = (Graphics2D)g;
    AffineTransform oldTransform = g2.getTransform();
    // 4. set the rotation transformation matrix
    g2.setTransform( AffineTransform.getRotateInstance( Math.toRadians( /*degree*/ ) ) );
    // 5. draw the BufferedImage on 'g'
    g2.drawImage( bi, 0, 0, this );
    // 6. reset the old transformation matrix
    g2.setTransform( oldTransform );
}And this suggestion will just rotate the drawn content. You have to resize and rearrange those Rxxx components you've created to fit with the rotated graphics.
