Add new type of component

Question

I want the user to be able to select which type of component gets added to each new tab in a JTabbedPane
for example, if the user opted to have a JTextArea in each new Tab
we could use
tabbedPane.add("new Tab", new JTextArea());
//But what if the user doesnt want a JTextArea they actually want a JButton, so this doesnt work
//or
JComponent newTabComponent = new JTextArea();
tabbedPane.add("new Tab",newTabComponent);
//this doesnt work as all swing components can only be child to one parent, so the op wont be able to add more than one tabany ideas how to implement this feature , thanks in advance

found out how to do it, heres an example
            JComponent c;
                try {
                    c = tabbedPane.getNewTabComponent().getClass().newInstance();
                    c.setPreferredSize(tabbedPane.getPreferredSize());
                    tabbedPane.add(c);
                } catch (InstantiationException ex) {
                    System.err.println("IE "+ex);
                } catch (IllegalAccessException ex) {
                    System.err.println("IAE "+ex);
                } catch (NullPointerException ex){
                    System.err.println("NPE "+ex);
                }
