Bilangual Highend theme with different domain names

Hi,
I would like to purchase the Highend theme for a bilingual site (Englisch and Dutch), but with different domain names for each language. I know I can do this using WPML, but do I really have to change the server settings like explained on https://wpml.org/faq/server-setting-for-languages-in-different-domains/? I read the article but I don’t understand anything about it. Isn’t there an easier way?
