java swing美化。。美化一点点就可以

如下，给我的jdialog加一个黑色的边框可以么？细细的一边就行。
没有框太丑了，但是也不要自带的那个蓝色的对话框的边，它太大。

public class Test extends JDialog{
	private static final long serialVersionUID = 1L;
	
	private JPanel imgPanel;
	private JPanel butPanel;
	private int myw=200;
	private int myh=400;
	public Test(){
		toFront();
		setUndecorated(true);
		setBounds(200,200,myw,myh);
		setLayout(new BorderLayout());
		setVisible(true);
		
		imgPanel=new JPanel();
		imgPanel.add(new JLabel("image"));
		
		butPanel=new JPanel();
		butPanel.setSize(myw,40);
		butPanel.add(new JLabel("text"));
		
		add(imgPanel);
		add(butPanel);
	}
	
	public static void main(String[] args) {
		new Test();
	}
}

butPanel.setBorder(BorderFactory.createLineBorder(Color.RED))
你看这样可以吗？试试吧！

这种效果？

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Graphics;

import javax.swing.JDialog;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class TestDia extends JDialog{
    private static final long serialVersionUID = 1L;
    
    private JPanel imgPanel;
    private JPanel butPanel;
    private int myw=200;
    private int myh=400;
    public TestDia(){
        toFront();
        setUndecorated(true);
        setBounds(200,200,myw,myh);
        setLayout(new BorderLayout());
        setVisible(true);
        
        imgPanel=new JPanel();
        imgPanel.add(new JLabel("image"));
        
        butPanel=new JPanel();
        butPanel.setSize(myw,40);
        butPanel.add(new JLabel("text"));
        
        add(imgPanel);
        add(butPanel);
    }
    
    @Override
    public void paint(Graphics g) {
    	super.paint(g);
    	g.setColor(Color.BLACK);
    	g.drawRect(0, 0, getWidth()-1, getHeight()-1);
    }
    
    public static void main(String[] args) {
    	TestDia td = new TestDia();
    	td.setVisible(true);
    }
}
