Using JFrame

I need some advice.































































































































I am preparing a small program with a user interface where:































































































































the user can choose between two buttons































































































































1- button then leads to a whole series of options































































































































button 2 - leads to another series.

is correct to create a java project and immediately do:

Java Code:

import javax.swing.JFrame;
public class TestInterface {

        public static void main(String[] args) {
                // TODO Auto-generated method stub
                
                JFrame frame = new JFrame("ExampleWrite");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                
                frame.setSize(1200, 600);
                frame.setLocationRelativeTo(null);
                
                frame.setVisible(true);
        }

}

and then build the buttons and reasoning on this interface?
