I want to make a panel with a text box and a button to execute and another to delete and another to copy from the clipboard

#
public static Panel CreatePanel()
{
    var panel = new Panel();

    var textBox = new TextBox();
    textBox.Location = new Point(10, 10);
    textBox.Size = new Size(200, 50);
    panel.Controls.Add(textBox);

    var button = new Button();
    button.Location = new Point(10, 70);
    button.Size = new Size(200, 50);
    button.Text = "Execute";
    panel.Controls.Add(button);

    return panel;
}

private void button1_Click(object sender, EventArgs e)
{
    var panel = CreatePanel();
    Controls.Add(panel);
}
