title: What GUI libraries does the spotify windows application use? Nice metallic borderless look?
body: <p>I think spotify in windows looks very nice, clearly not native windows gui.</p>
  
  <p>Seems to be completely borderless with a metallic look.</p>
  
  <p>I was wondering what libraries did they use to create such a nice looking app?</p>
  
  <p>Is it possible to create a nice looking app cross platform (well mac and windows really)?</p>
