title: how can I create own style for GTK and enforce it in my application
body: <p>I would like to create a custom style for GTK and /use/ that in my application.</p>
  
  <p>Even if I knew how to create the style, the application would use the style that is system default (or default choice of user who is running the application). Is it possible to override it, so that my application always use this my style (skin) created for it?</p>
