Simple installer-maker for minimal and graphical setup

Question

I want to make an installer that basically:

• Silently install other programs
• Run a shell script
• Clone a git repo

_{It's a way to solve File synchronization solution for controlling type of sync for subfolders and devices?}

I'd like it to have a creative way to impress users, maybe a slide of images during installation. Inno Setup doesn't seem to be able to do so.

At the end of the day, I decided to write a small Winform C# application for this. I was advised to stay away from Python (for its terribleness at GUI) and Node.js Electron (for its terribleness at memory: a simple hello world app requires you to run a whole instance of Chrominum). However, since the app is small and simple, I guess those weaknesses are not significant.
