1. I'm not native.
2. I can't read traditional Chinese.
Now, back to the subject at hand...
Although the grammar isn't too bad, I'm not sure exactly what you're trying to convey.
This might be better:
I'd like to learn and practice Chinese with you. I could help you with your Spanish.
ps: Chris' answer is wrong. Your sentence is still understandable, just not clear enough. His statement is just wrong.
