title: Windows Application That Displays Pop-Ups While Other Programs Are Running
body: <p>Firstly, I have zero experience programming with .NET so this could be a pretty nooby question...</p>
  
  <p>I'm wondering if it's possible to build an application like xFire - which displays pop-ups in-game to a user.</p>
  
  <p>As the primary application will have focus, how does my application manage to display it's message/popup?  Does the primary application have to allow access or something?</p>
  
  <p>Cheers!</p>
