The simplest client is a client. Popup window after transfer? On what?

Question

Python

Hello!
Can you please tell me the direction or place in which you need to dig? :)
Task: Local network for 200 computers. It is necessary to launch application "1" from the administrator and send a message to application "2" (installed on 200 computers), after transfer from the administrator, a modal window pops up in application "2" with a message that can be closed.
Please tell me in which language it is as easy as possible to implement such an application.
Of the features, this is constancy on the part of users, the ability to work in the background, placement in the tray. :)
C#, C++ ?
I ask for help and any thoughts and reasoning on this topic. Thank you.

Answer 1

If all 200 PCs have Windows, then maybe msg ?

Answer 2

if on all PCs not only Windows (and / or not only PCs) and there is a need to divide users into groups (send different text to different people), then you can install the jabber client on all workstations and use the bot for mailing (or through the server admin panel )
Pros: more flexible system, many ready-made solutions, easy to expand and increase functionality
Cons: you need your own jabber server or a stable Internet

Answer 3

I join the question with a little clarification: is Golang suitable for this task? In the sense, is there already a sufficient number of libraries "around" it to speed up / simplify the development of this functionality? In the same Delphi, for example, I threw a component on the form - the program itself is minimized to tray, I threw another one - the server is almost ready, etc.
PS Of course, I do not expect "visual programming" from Golang. ))

Answer 4

For a custom solution, I would take ZeroMQ, free, reliable, a lot of ready-made scripts, there are libraries for all major languages. The shell can be done in WPF (C#).
