There are optical character recognition programs available that can take Chinese text and transfer it into a text file, though it might generate a lot of errors. If you're willing, you could theoretically use an IME Pad to individually draw out characters. You can install an IME Pad for Chinese, Japanese and Korean text from the Microsoft Windows XP disc. Assuming, of course, you're running that operating system.
If you're just looking for a program that can take Chinese text and attempt to transfer it into English, you might want to have a look at Bing Translator:

Are you trying to work with Traditional or Simplified Chinese?
