I've been told by a variety of people that Dutch is fairly easy to learn.
I also happen to know that no South Africa dares speak Africans to a Dutchmen, as Afrikans is dismissed as 'Baby Dutch' or 'If your 10 year old kid spoke that bad you'd be seriously worried.'
Combining these two facts I would say that Afrikans is very easy to learn. Of course I have no evidence for this bar my own stab at learning Afrikans, which was conducted entirely in pubs and so isn't perhaps very representative.
