？
What kind of programming languages do you all like?
Literal
Everyone [topic-は] what-kind [genitive-の] programming-languages [subject-が] like is [question-か]?
A casual poll-style question. 皆さん ('everyone [polite]') is the polite plural form of 皆 — used in public addresses, classrooms, presentations, and polls. どんな ('what kind of,' 'what sort of') is the casual equivalent of the more formal どのような. The question targets a が-marked object of a な-adjective — 好き ('like') takes its object with が, like other adjectives of preference (嫌い, 上手, 下手). The combination 皆さんは[X]が[好き]ですか is the standard 'do you all like X?' frame. Plain everyday polite Japanese.
