C++/C# client application

I am looking for a strong C++ / C# developer(s) to work on a client application that displays realtime data. This application will be similar in look and design to MSN Messenger or Skype. And wil display user configurable requested data. Software will also allow alerts (similar to MSN messenger popups) to indicate when certain data has changed. Strong C skills are required as well as good graphic design integration knowledge.
