WPF - Japanese Handwriting Recognition without language pack

Question

Hi,

I'm developing a Japanese learning application in C#/WPF and am now trying to implement a Writing Practice mode which will take advantage of handwriting recognition.

I've been investigating a bit about Handwriting Recognition and various ways to achieve it. Though, wherever I look it always points me towards Tablet PC's and Language Packs. I myself does not own a Tablet PC and the most of the users does not have a Japanese Language Pack installed, so is it possible to achieve handwriting recognition without having a language pack installed? 

The built-in Microsoft IME does have an IME Pad which supports Japanese Handwriting Recognition without having to install a language pack, is there any API's available to use it in my own applications?

Any help on achieving Japanese Handwriting Recognition without a Language Pack and Tablet PC, would be greatly appreciated!

Regards,
Sukei.
