    public class BasicUI {
        public static void main(String[] args) {
            JButton button = new JButton("Label");
            JFrame frame = new JFrame();
    
            // Add button to the frame
            frame.getContentPane().add(button, BorderLayout.CENTER);
    
            // Set initial size
            int frameWidth = 300;
            int frameHeight = 300;
            frame.setSize(frameWidth, frameHeight);
    
            // Show the frame
            frame.setVisible(true);
        }
