Java SE (Java Platform, Standard Edition)

I have a situation where I have a load of buttons and a textfield (with label). When the user has the window maximized I want the buttons all in a line to save vertical space, however if the user shrinks the width of the window so the buttons no longer fit, I would like them to do the default Flowlayout, and go onto annother line. This works fine, except I need scroll pane for when the window gets so small as to start obscuring the text field.

I think this diagram shows what I need better than I can explain:

Here is an example showing my "problem"

import java.awt.*;
import javax.swing.*;
 
public class Test {
    public static void main(String[] args) {
    	JFrame f = new JFrame();
    	
    	JPanel parentPanel = new JPanel();
    	parentPanel.setLayout(new GridLayout(2,1));
    	
    	JPanel buttonPanel = new JPanel();
    	buttonPanel.add(new JButton("some"));
    	buttonPanel.add(new JButton("large"));
    	buttonPanel.add(new JButton("ammounts"));
    	buttonPanel.add(new JButton("of"));
    	buttonPanel.add(new JButton("buttons"));
    	buttonPanel.add(new JButton("!!!"));
    	
    	parentPanel.add(new JLabel("some short label, but still needs to be seen"));
    	
    	parentPanel.add(buttonPanel);

        //if the scroll pane isnt there it almost does what i want
    	f.add(new JScrollPane(parentPanel));
    	
    	f.pack();
    	f.setVisible(true);
    }
}

Thanks for any help
