Yeah, Spanish is pretty easy for Anglophones. Afrikaans is super easy for Anglophones to learn also. The syntax and pragmatics of Afrikaans are nearly the same as English. There are some new words, sounds, and orthography to pick up, but honestly the orthography is the hardest part. There aren't nearly as many resources to learn Afrikaans as Spanish, though.

Edited to add: Most Afrikaans speakers will tell you that Afrikaans is a dying language. That didn't stop me -- it's not much different from a programmer picking up Modula-3 just for the fun of it.
