In Korean, we say the same for ‘to be -ing’ form and ‘to do’ form. Although English sentences are different, you can say as ‘왜 한국어를 공부하세요? or 왜 한국어를 공부해요?’. Literally you can say 왜 한국어를 공부하고 있어요? (-하고 있다. means ‘to be verb+ing) but Korean people don’t say the way.

For the sentence-ending, there are different types of particles such as 세요?(하세요?) and 해요(-요). Both are formal, but 세요 is more polite. You can usually say 해요/-요 particle to end sentences.

For the future-tense, you can say ‘왜 한국어를 공부할 것이에요?’ Don’t forget to use the sentence-ending particle ‘에요’ at the end of the sentence : )

To write ‘Why are you going to study Korean?’ in Korean, you can write as 왜 한국어를 공부하려고 해요?
-하려고 하다 / or -려고 하다 means ‘to be going to / will ‘
