title: Simplest way to create a HWND
body: <p>I need a dummy window in MSVC++, this will never be visible and is created even before the app's main window. It's required by a rendering engine. So I'd rather not have to register a class if possible.</p>
  
  <p>For testing it would be better to make it visible to prove it is there - can I use a static or a button or something? I've been trying with CreateWindow() but while I am getting a return value, nothing visible is appearing.</p>
