"Yes, I want to learn Welsh."

Translation: Ydw, dw i eisiau dysgu Cymraeg.

If I want to use "moyn" instead of "eisiau", should it be "dw i'n moyn"?

I don't know if they're allowing "moyn" yet as a correct answer. The Welsh team said they were looking into adding dialects (i.e. "dach chi" AND "dych chi"), but I don't think they have yet. But yes, that would be correct; "Dwi'n moyn dysgu cymraeg."
