German and Dutch are the most closely related to English, but the Latin-based languages (e.g. French, Italian, Spanish, Portuguese) have a lot of vocabulary in common with English, and some people find them easier. In any case, Euroasia courses are carefully structured so that you are only introduced to language you can comfortably cope with, and this works for the Asian languages (like Chinese, Japanese, and Korean) as well.
Most languages are relatively easy to learn in the early stages. Check out some of our upcoming beginners courses.
