I don't speak Dutch but gesellig and gemütlich are two different concepts in German - although there is some overlap. You can most definitely be "gemütlich" all by yourself. Think cozy(ness).
And while Gemütlichkeit is a German word I don't think that the word is used much at all. Don't think I've ever used it - except when speaking to Americans who apparently think that the Oktoberfest is a prime example of the concept.
