title: Adding a new window in Cocoa
body: <p>I'm a beginner with Cocoa programming. All I wnated to know is how do I create a new window in Cocoa. I have created a NSViewController and window. As shown in tutorials I was able to add buttons to the MainMenu window and add actions to the buttons. Now I added a new NSViewController. I then went to plist file and made to load it first. My questions are as follows.</p>
  
  <p>When adding a new NSViewController, h m and xib files were created but the XIB file just has custom window and no other control elements like minimize max buttons etc.</p>
  
  <p>Secondly I added few elements and ran the file. The application ran but nothing was displayed on screen. Am I missing something.</p>
