How to 'inject' new functionality to a page?

Question

I need to create a button and then upon click invoke a flow. All this I need to do programmatically at runtime as the page I need to 'enrich' cannot be changed at design time.
Any pointers are appreciated.
Thanks,

I need to create a button and then upon click invoke a flow. By invoking a flow do you mean navigating to a control flow case ?
Anyways you can dynamically create a button (based on some trigger/event like click of another button etc) and attach an ActionListener to it. Something like this -
UIComponent parent = actionEvent.getComponent().getParent(); // this method is invoked within an ActionListener in my case which triggers the creation of a new button etc.
RichCommandButton button=new RichCommandButton();
button.setId("cmdBtn1");
button.setText("Ok");
button.addActionListener(new MyActionListener()); // attaching an ActionListener Class dynamically to the newly created button
parent.getChildren().add(button); // basically add the Button to an already existing container within the page
private class MyActionListener extends InvokeActionBean implements ActionListener{ // a class within the same Bean which holds the above method
public void processAction(ActionEvent actionEvent) {
//your Action Listener code to navigate to the flow here
