Hello everyone and thanks in advance.

I'm trying to do a very basic looking mines, but first I have to draw the "board" and I'm a bit stuck with that. I'm doing it with Java swing. With a Jframe and inside two Jpanel, one in which I enter the rows and columns that will have the board and a button that calls a method that draws the buttons automatically, but I can not get me to draw the buttons, because I have tried that the code creates the buttons and creates them, but next to the method, it does not create them. I attach code fragment of the method to see if you can lend me a hand.

public void ponbotones(int filas, int columnas){
    int pintar = 0;
    for(int i=0; i<filas; i++){
        JButton boton = new JButton(i+"");
        boton.setLocation(60*i, pintar);
        boton.setVisible(true);
        boton.setSize(50, 15);
        panel.add(boton);
    }
    for(int j=0; j<this.columnas-1; j++){
        pintar += 25;
        for(int k=0; k<filas; k++){
            JButton boton = new JButton(k+"");
            boton.setLocation(60*k, pintar);
            boton.setVisible(true);
            boton.setSize(50, 15);
            panel.add(boton);
        }
    }
    this.setContentPane(panelIntroduccion);
    pintar++;
}

jpPrincipal.setVisible(true);
        botones = new JButton[filas][columnas];
         for(filas=0; filas<botones.length;filas++){
             for(columnas=0; columnas<botones.length; columnas++){
                  JButton boton = new JButton();
                  boton.addActionListener(this);
                  botones[filas][columnas] = boton;
                  //botones[filas][columnas].setName(""+filas+columnas);

                  boton.setText("["+filas+","+columnas+"]");
                  botones[filas][columnas].setBounds(70, 30, 50, 30);

                  jpJuego.setBounds(400, 100, 300, 300);

                  jpJuego.add(botones[filas][columnas]);

             }
         }
    this.setContentPane(jpJuego);
