Friend, just keep your cool. Everyone faces exaaaaaactly the same problems. And know what, tuning is not a beginner thing, it will come at the stage when you are beginner-intermediate. A guitarist can tune perfectly only if his memory banks all the notes and there names. Once you understand the tuning logic and memorise the notes(the sounds, not the notes), then you will be able to tune instantly.And yeah, GB&A are superb beginner guitars.
Most websites mention tuning in the beginning part of learning, but it comes by itself when you learn the guitar. Basically they ask you to do so for getting the perfect sound off guitar. If u have a microphone then you may try this free software
