• use JPanel.get/putClientProperty ,

  1. you can to multiply this method

  2. every events this/these value, eg from Listeners

You are using absolute coordinates, a layout manager gives a better GUI across platforms, later Windows versions, accessibility etcetera.

MainConfig.page21.setLayout(new BoxLayout(MainConfig.page21, BoxLayout.Y_AXIS));

Also normally one would not need the JPanel, an event listener would know how to retrieve the panel.

Nevertheless you could maintain an array of JPanels:

List<JPanel> panels = new ArrayList<>();

In addPanel create a local variable, and add that

public void addNewPanel(int y, String title) { // Not static
    JPanel panel = new JPane();
    ...
    panels.add(panel);
}
