Multilanguage website with Dreamweaver CC

Hello everyone !!

In company we have developed a new website through Dreamweaver on HTML.
Currently the site is only in English and wanted to translate it into multiple languages.
I have to recreate all the translated pages or is there some other way?

Example: I want to make the site into German, the site contains 20 pages
I have to recreate all 20 pages translated into German, or there is some other system ??

Thank you all in advance for your help !!
