i recommend Node-red , i am also a noob i was not able to understand MQTT till I have seen it work with Node red, also you will find tons of benefits, i still use OH as my Hub, but node-red give me a powerful rule engine, that can perform complex tasks on is own, for example, i use it to send my IOS notifications
i am a big fan of node red , i think its the best way for non-programmers to get some real work done
