I wanted to honor my Polish ancestors by learning Polish, I am 50% Polish. I wanted to learn it easily as well, but I don't know how to.
I did the same, good luck with that. After you learn the basics on you own, I would recommend you the "Polonicum" summer courses at the Warsaw University, it's rather cheap for the good quality of the lessons, and they provide a dormitory accommodation : polonicum.uw.edu.pl/indexpl.php?lang=en
Some people learn Polish for very different reasons there: I even remember a Japanese guy learning Polish just for the love he had for Chopin's music.
By the way, as a French speaker, I found Polish way easier than German, for various reasons:
-Polish has a huge amount of French loanwords.
-the phrasal structure is very simple in Polish. In German, the verb changes its place all the time, and most of the time you have to wait to the very last word of a sentence to understand its whole meaning.
-in German you have to learn the gender of every single word (der/die/das) whereas it comes by itself in Polish as the gender depends from the last letter (-a is feminine, -o and -e are neutral, etc).
As for English, it's only considered as an "easy" language because of its huge influence both culturally en economically. But honestly speaking, the hardest part in English would be the pronunciation, which is absolutely irregular. Ask a beginner in English to pronounce the word "archive" for instance. As you see, it really differs from "achieve".
Same for other words like "tough/thought/though".
Listen at this poem and tell me if the English pronunciation is something easy to master: youtube.com/watch?v=m-JDu3o7Cyw
At least, the pronunciation is regular in Polish: you pronounce every word the way it's spelled.
