You probably don't want to use C++ for creating websites. It can be done but would be highly unusual. Go (golang) is probably a better choice as it has some built in libraries and tooling for back end servers. Otherwise, unless you really need high performance with thousands of users at once, Python is great. Just avoid PHP like the plague.
