>>50 Laos does not use latin letters. It uses the Lao script, which is extremely similar to Thai, in fact the two languages are somewhat similar in the way that English and Swedish are.

Speaking of Swedish, it probably wouldn't be too difficult for a native English speaker to learn, either.

Japanese is not all that terribly difficult either, although some seem dazed by the kanji. The most difficult thing for English (or other European languages) speakers to grasp seems to be getting 'wa' and 'ga' straight, among other challenges with particles, and the counters. But the pronunciation is pretty easy once you get the hang of it.

Many of Europe's languages, plus some of India's, are similar in grammar, so you have an advantage in learning another one if you already speak one. The one big thing for English speakers is the so-called "gender" of words - English is one of the few that doesn't have it.

As for >>9, Toki Pona isn't all that useful considering the lack of words. On a side note, I used to talk to the girl who made it and to be honest, I think she's a bit strange.
