Weis da einer bescheid
gibt es da einfache Möglichkeiten ohne gleich 500 Lines of Code schreiben zu müssen
oder gibt es ein Java GUI TOOL der das für einen macht!

import java.awt.GradientPaint;
import java.awt.Graphics;
import java.awt.Graphics2D;

import javax.swing.BorderFactory;
import javax.swing.Icon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.border.BevelBorder;


public class JFrameSample extends JFrame{

	
	private JPanel panelTree 		= new JPanel();
	private JPanel panelImage 		= new JPanel();
	private JPanel panelWhatEver 	= new JPanel();
	
	public JFrameSample(){
		initGui();
	}
	
	private void initGui(){
		this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		this.setLayout	(null);
		this.setSize	(800, 600);

		
		JLabel label = new GradientLabel("Test");
		label.setForeground(Color.white);
		this.panelTree.setBounds	(25, 25, 350, 250);
		this.panelImage.setBounds	(25, 300, 350, 250);
		this.panelWhatEver.setBounds(425, 25, 350, 525);
		
		this.panelTree.setBorder(BorderFactory.createBevelBorder	(BevelBorder.RAISED, Color.LIGHT_GRAY, Color.GRAY));
		this.panelImage.setBorder(BorderFactory.createBevelBorder	(BevelBorder.RAISED, Color.LIGHT_GRAY, Color.GRAY));
		this.panelWhatEver.setBorder(BorderFactory.createBevelBorder(BevelBorder.RAISED, Color.LIGHT_GRAY, Color.GRAY));
		
		panelWhatEver.setLayout(new BorderLayout());
		panelWhatEver.add(label, BorderLayout.NORTH);
		this.add(panelTree);
		this.add(panelImage);
		this.add(panelWhatEver);
	}
	
	public static void main(String[] args) {
		new JFrameSample().setVisible(true);
	}
	
	private class GradientLabel extends JLabel{
		
		
		
		public GradientLabel() {
			super();
			
		}

		public GradientLabel(Icon image, int horizontalAlignment) {
			super(image, horizontalAlignment);
			// TODO Auto-generated constructor stub
		}

		public GradientLabel(Icon image) {
			super(image);
			// TODO Auto-generated constructor stub

		public GradientLabel(String text, Icon icon, int horizontalAlignment) {
			super(text, icon, horizontalAlignment);
			// TODO Auto-generated constructor stub
			
		}

		public GradientLabel(String text, int horizontalAlignment) {
			super(text, horizontalAlignment);
			// TODO Auto-generated constructor stub
		}

		public GradientLabel(String text) {
			super(text);
			// TODO Auto-generated constructor stub
		}

		public void paintComponent(Graphics g) {
			// TODO Auto-generated method stub
			
			GradientPaint paint  =new GradientPaint(10F, 0F,Color.blue,getWidth()-10, 0F, getBackground());
			
			Graphics2D g2d = (Graphics2D)g;
			g2d.setPaint(paint);
			g2d.fillRect(0, 0, getWidth(), getHeight());
			super.paintComponent(g);
		}
		
	}
}
