title: How to call controller from custom menu created by extension in Magento?
body: <p>I am new to Magento and at first up i got the task to create Magento Extension. So i am reading from the internet and creating extension. My Magento version is 1.7.0.2.</p>
  
  <p>I am able to create basic structure of extension and kept config.xml and other files at proper place which made my extension to install properly in Magento but now i want to call my controller from my menu which i added in main navigation in admin section. This is my config.xml file, please tell me what i am doing wrong here which is not letting me call my controller from my menu.</p>
  
  <pre><code>&lt;?xml version="1.0"?&gt;
  &lt;config&gt;
  &lt;!-- turn on our module, required for install support --&gt;
  &lt;modules&gt;
  &lt;Gwb_Magecrmsync&gt;
      &lt;version&gt;0.1.0&lt;/version&gt;
  &lt;/Gwb_Magecrmsync&gt;
  &lt;/modules&gt;
  &lt;global&gt;
  &lt;helpers&gt;
      &lt;magecrmsync&gt;
          &lt;class&gt;Gwb_Magecrmsync_Helper&lt;/class&gt;
      &lt;/magecrmsync&gt;
  &lt;/helpers&gt;
  &lt;!-- turn on models --&gt;
  &lt;models&gt;
      &lt;magecrmsync&gt;
          &lt;class&gt;Gwb_Magecrmsync_Model&lt;/class&gt;
          &lt;resourceModel&gt;Magecrmsync_mysql4&lt;/resourceModel&gt;
      &lt;/magecrmsync&gt;
  &lt;/models&gt;
  &lt;!-- turn on models --&gt;
  
  &lt;!-- turn on database connections --&gt;
  &lt;resources&gt;
  &lt;!-- setup is needed for automatic installation --&gt;
      &lt;magecrmsync_setup&gt;
          &lt;use&gt;default_setup&lt;/use&gt;
