I finally managed to move my personal blog from Wordpress to Hugo: www.c-m-l.net
The project took quiet some time, I guess around six months. Especially finding and modifying a theme and understanding the concept behind Hugo were quiet time consuming. However, in the end I found Hugo less complex than Wordpress and its thousands plugins and much more pleasant to work with. Also I am not a developer but a social scientist with a family and a full-time job, so I can work on the site only in my spare free time.
I guess that there are still many rough edges on the site which need polishing, so I really appreciate any feedback.
