title: Dynamic FormType creaton and serialization
body: <p>I was wondering if there is a way to dynamically create forms in Symfony from GUI. I'd like to build a GUI for form creation, so I could inject form to some templates from GUI and not hard code it.</p>
  
  <p>I would create hooks in template to dynamically add forms.</p>
  
  <p>There are similar things in WP and Drupal already.</p>
  
  <p>I hope I've verbalized what I wanted to say.</p>
