    What is the variable name for the "inside component"?

    You need to create a jframe and add the jpanel component to it. jpanel cannot be displayed on its own.
    so you can modify the code as

    JFrame jframe1 = new JFrame("NewFrame");
    frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLO SE);
    JPanel jPanel1 = new javax.swing.JPanel();
    JLabel jLabel1 = new javax.swing.JLabel("how r u");
    JButton jButton1 = new javax.swing.JButton("yes");
    JTextField jTextField1 = new javax.swing.JTextField();
    JPanel1.setLayout(new FlowLayout());
    jPanel1.add(jLabel1);
    jPanel1.add(jButton1);
    jPanel1.add(jTextField1);
    jPanel1.setVisible(true);
    jframe1.add(jPanel1);
    jframe1.setSize(400,400);
    jframe1.setVisible(true);

    Hope this solves your problem
