I want to learn about English, because I think I can't speak English well;.

I think I can't speak English well;, (*)
so I want to make be freinds friends with(**) anyone who/that (***)knows how to speaks English^^;. (****)
And My native language is Korean, so
if you are learning (*****) about Korean, please send me a friend request!
I wish hope I could can (******) be your good friend:)

*The semi colon (;) is used for joining clauses without a conjunction like: For, And, Nor, But, Or, Yet & So. If you are using "So", you can use a comma to divide clauses.

** Alternatively you can say "make friends that speak English", but that way you wouldn't use the "anyone".

*** In this case either "who" or "that" are acceptable.

**** This should be the end of the end of the sentence because the next part is more related to the sentence that follows.

***** Depending on what you want to say, you can also use "if you want to learn Korean"

****** "I wish I could..." is more commonly used to describe something you regret you can't do and would like to change

e.g. I wish I could fly, buy I'm not a bird.

"I hope..." Is used to describe something that you are expecting to happen

e.g. "I hope I can get tickets to the Super Junior concert".

I hope this helps you ^^

안녕히계세!
