Making a website is not very difficult. It’s not, not really.
I am biased because I am a website developer, so I can build a website quite easily, but I could give you instructions and you could go from having no website to having a website in the space of 30 minutes, perhaps less.
Naturally, there is a catch. That assumes that you want
A website …
… that can be accessed (so it works) …
… on any device that can connect to the Internet …
… and nothing more. If that’s what you want, there are places that you can go to where you can come out with a website in a matter of minutes. You could even get your own domain for a few quid too. Little to no effort required. If that is all you want. And I’m willing to bet it isn’t. There are many ways to create a website. Such as CSS/HTML, WordPress, Wix, blackjack77australia.com etc. If you learn about how to create a website, you can do it easily. I will suggest that WordPress is a very easy way to make a website. It also takes a small time.
