Help with gaps in GridLayout

[trill]

Hi, I have a grid, with 12 buttons in it. Once displayed there is a small gap inbetween the buttons, maybe 5 pixels. I have been using the setHgap and setVgap methods to try and get rid of this gap but cannot. Can it be done?

import javax.swing.*;
import java.awt.*;

class MainPanel extends JFrame{

	Container container = getContentPane();
	JPanel gamePanel = new JPanel();

	String[] buttonsImageNames ={

				"bart0.jpg",
				"bart1.jpg",
				"bart2.jpg",
				"bart3.jpg",
				"bart4.jpg",
				"bart5.jpg",
				"bart6.jpg",
				"bart7.jpg",
				"bart8.jpg",
				"bart9.jpg",
				"bart10.jpg",
				"bart11.jpg",
				};
	JButton [] buttonArray = new JButton[buttonsImageNames.length];
	Insets buttons = new Insets(0,0,0,0);
	ImageIcon [] imagesArray = new ImageIcon[buttonsImageNames.length];
	GridLayout layout = new GridLayout(0,1,0,0);


	public MainPanel()

	{
		setTitle("Jake's Cash Machine!");
		setSize(500,430);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

		for(int i=0; i<buttonsImageNames.length; i++){
			buttonArray[i] = new JButton(new ImageIcon(buttonsImageNames[i]));
			buttonArray[i].setMargin(buttons);
			gamePanel.add(buttonArray[i]);

		}

		container.setLayout(layout);
		container.add(gamePanel);
		container.setBackground(Color.white);

		System.out.println(layout);

		setVisible (true);

	}
}

Thanks.
