I'm working on a website for a Swedish artist and her page is in Swedish, everything is in Swedish on the site, even though it's not a lot of text on the site. We would like to have the site in English too, or another version of the site in English on a separate domain, what's the best way to proceed from here?

The domain name is a .se (swedish domain), would it be better to create a another domain and host the english version of the site on a .com domain? Or will we bump into problems with duplicate content if we create a replica of the swedish site in english.

We're using wordpress and I know that there's translation plugins out there, is that a good option?

I'm a bit clueless on how to proceed and would love some help or guidance here.
