daniel added a comment. The information which wikipedias have an article about an item is "local" to the item, that is, it's directly contained in the item's JSON blob, as a "sitelink". There is no need for an actual "query" (wikidata "queries", WDQ or SPARQL, generally return lists of items).
So, this API request ("query", of you want) tells you which wikipedias have an article about douglas adams: https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q42&props=sitelinks. Finding out which wikis //don't// have such an article is then just a matter of comparing the result to a list of all wiki projects you are interested in. Now, if you wanted to ask something like "which items about 19th century painters do not have an article in the russian wikipedia", you'd need a SPARQL query.
