When farming starts no coding or technical skills will be needed. See: Hi I'm new and spent about an hour but am still not super clear about a couple things - #5 by JimCollinson
For development it depends on what you want to build, the approach you take (web app, native mobile app, desktop etc) but in general most common languages will be usable because the APIs will come with ‘bindings’ that make them available to different languages.
Your question has been asked before, so searching this forum (and also the dev forum) you’ll find more detailed discussions of options. Once you have an idea what you want to build or have decided on the approach you can ask more specific questions.
Welcome and good luck!
