在没有 Gui 编辑器的情况下向 Gui 添加 3 个 jTextArea

Question

我接了一个学生的作业，我的任务是为它写一个自动单词编译，快完成了，我遇到了一个问题。我必须向 gui 添加 3 或 4 jTextAreas。问题是他怎么写的代码我只能加一个jTextArea.

这是 1 的样子 Jtextarea:

这就是我希望它拥有它的方式：

这是管理键盘孔布局的代码：

            button = new CustomJButton[button_size];
            jPanel1 = new javax.swing.JPanel();
            jPanel2 = new javax.swing.JPanel();
            jTextArea = new javax.swing.JTextArea();

            // BorderLayout
            bl = new java.awt.BorderLayout(); 
            this.setLayout(bl);
            this.add(jTextArea, BorderLayout.NORTH);
            Font font1 = new Font("SansSerif", Font.BOLD, 20);
            jTextArea.setFont(font1);
            jTextArea.setFocusable(false);



            menuButtongbc = new GridBagConstraints();
            // vergrößert die Buttons in BEIDE Richtungen // HORIZONTAL / VERTICAL
            menuButtongbc.fill = GridBagConstraints.BOTH;
            menuButtongbc.insets = new Insets(1,1,1,1);
            menuButtongbc.weightx = 1;
            menuButtongbc.weighty = 1;

            letterButtongbc = new GridBagConstraints();
            // vergrößert die Buttons in BEIDE Richtungen // HORIZONTAL / VERTICAL
            letterButtongbc.fill = GridBagConstraints.BOTH;
            letterButtongbc.insets = new Insets(1,1,1,1);
            letterButtongbc.weightx = 1;
            letterButtongbc.weighty = 1;

            jPanel1.setLayout(new java.awt.GridBagLayout());  // Layout left side
