I love building UIs with HTML and I am ok with building JavaScript. BUT this would not be the solution. People would still run different html and js engines and everything would be a mess. Not to mention the js ecosystem with its dependency creeps isn't known to be efficient. There have been and are plenty of other multi platform languages that have less platform issues. Like: Java or Haxe. That said I am pretty sure gnome shell comes with a complete js API.
