What to start developing in c++?

Question

C++ / C#

Hello! I used to write simple programs in pascal, now I decided to switch to c ++ and start developing desktop applications for windows. As a goal, I chose a media player with the ability to view photos, movies, listen to music. It is I who want to create a program with a pleasant, simple interface and ease of interaction. So, where to start, what to take as a basis, how to develop a design (it is desirable that everything be in one program). Thanks in advance everyone!

Answer 1

So start gradually. Write a utility for listening to an mp3 file, ogg ...
Another one for viewing pictures.
Third video.
The fourth is something with databases so that later it can be cached and it is easier to index all this economy.
Finally, try something in the GUI
Because, without the experience of developing this whole economy, it is impossible to make such a combine that you have planned. And experience is better to gain gradually.
