title: how to make custom module in magento 1.7
body: <p><strong>How can the following be accomplish in Magento?</strong></p>
  
  <p>Display a "Hello World" message using a controller/view/model approach. So, if I went to <a href="http://example.com/myController" rel="nofollow">http://example.com/myController</a> it would show the string 'Hello World'. Being able to show this string within the template of my website (for example, the header, footer, etc.) will be a bonus.</p>
  
  <p>How to add a method to this controller (or a new controller if necessary), which interacts with a model, and performs the query <code>Select * FROM articles where id='10'</code> and returns the row (containing the columns <code>id</code>, <code>title</code>, <code>content</code>) to the controller? </p>
  
  <p>And then use the controller to include a view, which would display this row. So going to <a href="http://example.com/myController/show_row" rel="nofollow">http://example.com/myController/show_row</a> (or something similar) would display the row within a view. (No need to be fancy, just a echo <code>$row-&gt;id</code>; or something similar would work.)</p>
