Here's a link for those interested in Gaelic as well as Irish.http://www.learngaelic.net/lg-beginners/
I am very glad you have an interest! :) It's a fantastic language, and really, it's not that hard, even though it seems a bit intimidating to beginners. I'm a learner myself. I'm near-fluent/fluent-ish, trying to get my Gaelic to be more native-sounding and improve my listening skills. Not easy when you live on the other side of the globe from most Gaelic speakers! But of all the languages I've studied, I have found Gaelic the most rewarding, not simply because of my Scottish roots. Learning Gaelic has made me a better language learner all around and it's just so much more fun to speak and listen to than my native English. ;)
A little more detailed explanation: the Gaelic languages are a group of 3 Northern Celtic languages all descended from Old Irish, and the people who speak these languages are collectively known as the "Gaels", hence why the languages they speak are all called Gaelic. And in each of the three languages, the name for them simply translates into English as "Gaelic", or "the language of the Gaels": Gaeilge (Irish Gaelic), Gealg (Manx Gaelic) and Gàidhlig (Scottish Gaelic). But due to time, distance and how each of these languages have evolved on their own paths from Old Irish, they are considered each their own language from a more scholarly, academic and linguistic point of view, despite there being obvious similarities. Irish Gaelic today is offically known as simply Irish in English, while colloquially it may still simply be called "Gaelic" in Ireland, just as Scottish Gaelic is simply "Gaelic" colloquially in Scotland, and Manx Gaelic is simply "Gaelic" colloquially on the Isle of Man. But thanks to popular culture outside of Ireland, Scotland and the Isle of Man that conflates these three Gaelic cultures into one Irish-y cariacture, people tend to overhwhelming associated "Gaelic" with simply Irish, and usually are fairly ignorant that Gaelic actually refers to a group of languages spoken by Gaelic peoples in three different Celtic nations and not simply in Ireland.
