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

public class page1 {
    JFrame frame;
    JButton play,settings;
    page1()
    {
        frame = new JFrame("GameName");
        frame.setSize(200,200);
        frame.setLayout(new FlowLayout());
        play = new JButton ("Play");
        settings = new JButton ("Settings");
        frame.add(play);
        frame.add(settings);
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    public static void main (String args[]) {
        new page1();
    }
}
