Write some Software

I need a solution architecture to deploy a medical imaging system. It should be able to send/receive/view data from a central node. The systems works in a closed network. The solution needs to be open source. I don't need any deliverable for this, but just the solution (softwares to be used as client and sever). It can be C++,C# or Java or combined, without any dependency in the code. That means, if the open source version changes, I should be able to update my version without having any further work. Due to some reasons, cannot use DCM4CHEE.
