@Bacon Veep:
There are websites that categorize languages, along with printed material (books, encyclopędias, etc.).

Thai is tricky. I have a traveller's level of Thai, but I'm no where near fluent. Thai (and other S-E Asian languages), though much easier for Westerners than Mandarin, Japanese and Arabic, are certainly trickier than European languages for us. Consider that you'd probably find Russian easier
French vs. Spanish? Spanish is inevitably a winner in easiness for Anglophones.
Granted probably a plurality of English vocabulary comes from French (or from Latin through French), but that vocabulary is also incredibly similar to Spanish.
Spanish has only one auxiliary verb (so you don't have to care too much whether a verb is transitive or intransitive), has fewer exceptions and no nasal sounds (for the monolingual English speakers who struggle with the nasal sounds). Spanish is easier than French regardless of your first language (unless your first language is Spanish, French, or a really similar language like Catalan or Portuguese, and even then you'd probably find Spanish easier), because Spanish is pretty much an easier language in all aspects. The only thing I could think of that would be easier for English speakers in French would be for/by (pour/par), which lines up with English much more than in Spanish (para/por). Once you tackle para/por in Spanish, pretty much everything else is easier than in French. Oh, and Spanish might trick you on the masculine/feminine thing...not all words ending in "a" are feminine. Already knowing French will make this a freebie for you, because 98+% of words are the same gender in both languages. Seeing as French and English are both my first languages, I cannot explain why a word is either masculine or feminine (I can tell you all the rules for German, but not the Latin languages). When I learned Spanish, I learned the differences on a case by case basis, seeing as there are so few of them. Spanish will probably seem easier for learning masculine/feminine, but then will trick you at times, whereas French will probably require you to learn the "logic" behind it a little more because it's a little less obvious going by word ending, but you won't get "tricked" once you've got the logic figured out.
If you want to learn both, I would recommend learning French first. It's a little trickier, and once you learn those subtleties about grammar (like transitive/intransitive verbs), if it's ever mentioned in your Spanish lectures, you can already appreciate it when learning about, say sentence structure, and enjoy the fact that you won't have to even think about it when formulating sentences in Spanish on the fly
