My friend is Spanish and knows little English.  Enough to get by. I have googled and I can never find a place to buy a book other than in English.

I have no real knowlegde, but perhaps from Spanish book shops. (he/she does not live in Spain I gather) So probably from one of them you can order it abroad. I know in Finland it is much easier to get books in Finnish than in English, so I would recommend for he/her to look for Spanish online stores.

Not to be vague, but I think you can google or something similar for one. I don't understand Spanish, so I cannot know what is out there, as through Europe you seldom find translations, but as in Finland, and Spain is a tad larger, you should find online stores.

Los Espejos de la Rueda is the only spanish language WoT site that I know of. http://espejosdelarueda.org/'>http://espejosdelarueda.org/

 

I can't make heads or tails of it, but it's possible they'll have a source for you.

The spanish language publisher is Timun Mas, you can buy the books at http://www.scyla.com/sagas/46/fantasia_epica/rueda_tiempo

 

Please note the first few books have been divided so that the series in spanish consists of 18 books (19 with  New Spring).
