I don't think the language that a programming question is related to has anything to do with whether it is on topic on this site. The rest of this answer concerns whether programming is on topic.
IMHO questions concerning actual programming should be off-topic here, whatever the language; there are plenty of specific SE sites that cover that as well as the more general StackOverflow.
However, I can see there being relevant questions here relating to programming (and associated topics such as source control, collaboration, etc), concerning best practices for open science. There's going to be a fine line of relevance on what is specific to science and what is good practice anywhere (something commonly called "boat programming" questions), which will need judgement and not reflexive close-votes once things are underway.
