How to implement a training program and what is needed for this?

Question

C++ / C#

Good day. The other day they gave out topics for graduation theses at the technical school. I decided to start developing an application like a tutorial, but I ran into a problem. How to implement this project, and what languages ​​and development environments to use?
PS I have basic knowledge of C++, Html, Css, Javascript, Php, Windows Form and MySQL.

Answer 1

What languages, technologies and environments you own - use them. Because there are no details about what kind of "training manual" - then you can answer like this. If there is a more detailed statement of the problem - proceed from it. For example, they require that there be accounting for users + cross-platform - use Php. It is possible standalone - try with ++. You just need the output of articles and pictures - pure HTML + JS is also possible.

Answer 2

implement in a playful way depending on your knowledge

Answer 3

As far as I understand, you need to transfer data about counters to a new window that opens. To do this, you can use several options:
1. Cookie (when you click on the window creation button, we send a request to the server where our button is added, returns true and only after we show the window.)
2. Session (the same as with Cookie)
3. Session Storage / Local Storage (this option will be much faster)
