In summary, the conversation is about using the gridlayout to create a specific shape in a GUI. The speaker mentions using an empty label to add an empty grid and shares their code using gridlayout and for loops. They also mention using the Netbeans GUI editor and suggest using grid bag layout for complex layouts. The speaker admits to not having much knowledge about the topic and is trying to learn.

This is my code:
Java:
import javax.swing.*;
import java.awt.*;
public class test {
    public static void main(String[] args) {
        JFrame frame = new JFrame();
        frame.setTitle("Buttons");
        frame.setSize(800, 800);
        int size=12;
        int flag1=0,count=0,count2=0;
        frame.setLayout(new GridLayout(1,2,0,0));
        JPanel panel = new JPanel();
        GridLayout layout = new GridLayout(size,(size*2),0,0);
        panel.setLayout(layout);   

        for(int i=1; size>=i; i++){         
            for(int k=0; i-1>k; k++){
                panel.add(new JLabel());  
                count2++;            
            }
         
            for(int k=0; size>k; k++){
                JButton button = new JButton(""+i);
                button.setBackground(Color.WHITE);
                panel.add(button);
                count2++;
            }
         
            for(int k=0; (size*2)-(count2)>k; k++){                  
                panel.add(new JLabel());
                flag1=1;                                   
            }
            if(flag1==1){
                    count2=0;
                    flag1=0;
            }

        }

        frame.add(panel);
        frame.setVisible(true);
    }

I would use the Netbeans GUI editor to do complex layouts and for this layout, I think grid bag layout is better.
