How to make a desktop agent for a website?

Question

PHP

Good day everyone!
There is:

• several machines/computers on which the program/script will be installed
• website in PHP with the ability to export in almost any format

Necessary:

• When a new entry or news appears on the site, a "pop-up" in the tray and playing a sound signal
• There are 2 buttons in the popup dialog: "yes" and "no"
• Identification of users / machines by nickname (previously entered in the program settings)
• Sending a yes/no response and an ID to the site
• Maximum Compatibility

I thought in the direction of DevelStudio, but I don’t know how rational it will be to use it.
Please share your experience ;)

Answer 1

An RSS reader was implemented in the form of an alert program. Required functionality is covered.

Answer 2

Judging by the description, you do not need a desktop application, you need the alert functionality.
Latest Safari and Chrome support html5-notifications which fully covers your functionality.

Answer 3

NW.js
App.js

Answer 4

I would suggest using SignalR from the server side and the client application is easily written in C#
