I'd add to the above Dancer2 because is very easy to start with. Start with the Dancer2::Tutorial

In my experience, as you are on windows, forget to configure IIS to run your perl code: is a stress and many time with a dead end.

Go instead with some PSGI (instead of CGI) aware server that can run decently on windows: I had luck with Twiggy with a simple command line launcher:

C:\perl5.26-64\perl\site\bin\twiggy.bat  --listen 127.0.0.1:80 c:/scripts/miniproject/bin/app.psgi

See also a mini project of mine using Dancer2 (nothing impressive: was my first serious attempt)

For the database connection perhaps starting with sqlite is good enough.
