我想学汉语。

我很喜欢汉语！請問誰(see Note1)可以(=能夠)帮助我(學習漢語)呢？我可以帮助你您(see Note2)学習德语或意大利语。

Notes:

Since you can speak English, I beleve explaining to u in English is more easyer.

1. We all wanna speak a language in official and polite way. So, it is better to say 'PLS' in the begining of an asking. :) Thus, the sentence will be:

Who (can) help me (to learn Chinese) , please?

Of course, you can ignore the words in (). The meaning of the sentence is still completed in Chinese.

2. In Chinese, we do have 你 (as German's du) and 您 (German's Sie). Since this is an asking, I think using 您 is better than 你. But, it is still ok for us.

Btw, I am a Taiwanese and I can only type the form of words in traditional Chinese. But, it is easy to transfer traditional Chinese into simple. Mr. Google Translation is always kind for helping ladies. :D
