This code attempts to explain why layouts and preferred sizes are so important. The important part lies in the input/output.

TestGuiSize.java

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

class TestGuiSize {

    public static void addButtonToPanel(JPanel panel, String label) {
        JButton button = new JButton(label);
        button.setMargin(new Insets(1,1,1,1));
        panel.add(button);
    }

    public static void main(String[] args) {
        JPanel p = new JPanel(new GridLayout(4,3,3,3));
        addButtonToPanel(p, "7");
        addButtonToPanel(p, "8");
        addButtonToPanel(p, "9");
        addButtonToPanel(p, "/");

        addButtonToPanel(p, "4");
        addButtonToPanel(p, "5");
        addButtonToPanel(p, "6");
        addButtonToPanel(p, "*");

        addButtonToPanel(p, "1");
        addButtonToPanel(p, "2");
        addButtonToPanel(p, "3");
        addButtonToPanel(p, "-");

        addButtonToPanel(p, "0");
        p.add(new JLabel(""));
        addButtonToPanel(p, "Del");
        addButtonToPanel(p, "+");

        Dimension d = p.getPreferredSize();
        System.out.println(
            "Preferred Size: " +
            d.getWidth() +
            "x" +
            d.getHeight());

        JOptionPane.showMessageDialog(null, p);
    }
}

Run-time parameters are just the tip of the iceberg of the differences between runs that might sink an application's GUI code. Layouts are designed to handle such differences.
