Creating a NTP client with no prior network programming experience. Where do I start?

I have a task to implement a NTP client in C/C++. I have not done much programming in the networking area before and i'm not really sure where to start. Eventually this NTP client needs to be implemented in an embedded system, but I figured it would be wise to start out easy and implement it in a pc program first and then continue from there.

I've read through this: http://ift.tt/1GFYnxp, but I didn't get much wiser as to where to start. Any help to get me started would be greatly appreciated
