title: Create admin front with a simple form via a module [Magento]
body: <p>I am pretty new to Magento and am trying to understand how to create admin (backend) page. I have figured how to create/define the controller and action (along with editing the config.xml).</p>
  
  <p>But now the next problem at hand is to display a simple form in that page. I understand that, I have an option to create blocks and mention the blocks in a layout.xml. But from what I figure is that layout.xml needs to be present in the theme folder. Which I can't do as my magento extension will be installed and I have no access to the user's system.</p>
  
  <pre><code>So the doubt is. How to display a simple from in a backend (admin) page 
  without having to make any changes to the theme's layout ?
