    To get better help sooner, post a SSCCE (Short, Self Contained, Compilable and Executable) example that demonstrates the problem. Your problem is achieving a GridBagLayout with spaces between buttons, so post code that makes a GUI with only 2 to 4 buttons in a GBL.

    ok I modified my code and made the code with two buttons. Please help me figure out how I can add horizontal and vertical spaces. Here is my new code.
    Java Code: 
    package test.gui;

import javax.swing.JPanel;
import java.awt.GridBagLayout;
import javax.swing.JButton;
import java.awt.GridBagConstraints;
import java.awt.Insets;
import javax.swing.ImageIcon;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;

public class layer1 extends JPanel {

	public layer1() {
		GridBagLayout gridBagLayout = new GridBagLayout();
		gridBagLayout.columnWidths = new int[]{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
		gridBagLayout.rowHeights = new int[]{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
		gridBagLayout.columnWeights = new double[]{0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, Double.MIN_VALUE};

		setLayout(gridBagLayout);

		JButton btnNewButton_2 = new JButton("button3");
		btnNewButton_2.setIcon(new ImageIcon("Images/pic4.gif"));
		GridBagConstraints gbc_btnNewButton_2 = new GridBagConstraints();
		gbc_btnNewButton_2.insets = new Insets(0, 0, 5, 5);

    GridBagLayout does not reserve space for rows and columns that contain no components.
