title: Is it a bad idea to run WxWidgets and GTK?
body: <p>I'm currently writing a media player in Ruby (called <a href="http://shroom.rubyforge.org/" rel="nofollow noreferrer">Shroom</a>) with a GTK interface, but I use WxWidget's MediaCtrl for cross-platform audio playback abstraction. I don't want to use WxRuby for the interface as well, as I need to work with GTK's TreeView.</p>
  
  <p>What kind of performance problems may arise from this? Is it so bad to have two main loops?</p>
