There are very good Web Servers on the market, Apache and NGINX to name a few. However, to interface your backend code you need to use Apache modules or WSGI/FastCGI with NGINX (depending on your language of choice). To actually use a fully integrated environment you need to use something like Django or Tornado for Python. For GO there is a small built-in web server that allows you to build up a more robust environment around it.
