Zend form in WordPress page

I created a Zend 2 application that displays a Form calling the addAction() in my Controller (url: .../my-app/add) and using the add.phtml for the layout.

Now I would like to integrate this form in a wordpress page using a shortcode. So I created a wordpress plugin that integrates the Zend 2 Framework in my wordpress application.

First question: How can I make the call to .../my-app/add in order to display the form within a wordpress page?

Second question: How can I tell wordpress to let my Zend Application handle certain requests (e.g. all request starting with …/my-app/)?

Thank you for your help.

I am using Zend Framework 2 (2.4.2), php 5.5.9 and WordPress 4.3.1
