Hi Alex,
I am interested in developing your time display application.
The specs you have written are simple and I don't see any issue in developing the solution quickly.
I will program in C++ using Qt framework, on Windows (preferably). I can also build for Linux and Mac.
I will handover the complete solution, including source code, to you.
I can look after the life cycle support of this application for long term, and I can also offer you ideas to enhance its capability.
For example, maybe add a stocks ticker to it in future, and maybe other alerts.
I am available for Skype meeting, at any time you like.
Regards.
Umair.
