make desktop sms application using windows mobile 6.1

I have to make a SMS sending application in .NET which uses a connected CDMA based Windows mobile 6.1 device to send sms. The problem is I have never worked on smartphone app development so don't have any idea about how should i go about it. Couldn't find anything useful on SO or elsewhere, so please guide me in the right direction.

Thanks in advance to all those who reply.

This is the native library for sending SMS from the cell phone itself.

Microsoft SMS Sender may do what you need without writing any code at all.
