Regarding the process, Paul commented:
Was a pleasure to translate this page! It's kinda fresh and related to my professional interests, so I thought - why not, if the author allows to do so.
The translated page is at URL: http://www.movavi.com/opensource/3DNA-be. Interestingly, when I used Google Translate to convert the Belorussian version back to English, the outcome is pretty readable. In contrast, when the original English version is directly translated to Chinese, the result is beyond recognition!
