Showing Chinese Characters in English NT

I have a question about Font Association. Is there a way to map any English fonts in my application to a Chinese font without using any of the 3rd party software?
In other words, if all my stuff are selected using Arial font, but I want to associate a Chinese font with Arial so that if my string has Chinese characters, it will be smart enough to go look at the Chinese font instead of Ariel. Is there anyway to achieve that kind of association on English NT?
Thanks in advance.

You can simply select a Chinese font, for example "MS Song" and the display
will automatically be Chinese if it is in the right Chinese encoding, like GB.

No, I am not talking about Chinese Windows XX. I am talking about the plain
English Windows NT. You do need to load the Chinese font into the system first.
