Is it possible to add a small online store inside the site and how to do it?

Question

IT education

Hey!
I am doing my thesis. I put together a site in Mobirise, but, unfortunately, there is no template for selling goods. I want to manually change the source.
What you actually need: there are three products. When you click the buy button, a page should open with a choice of color (t-shirt), size, payment system, etc. In layout and programming, I, if not zero, then 0.5, so maybe someone has at least approximate instructions or ready-made code on how to do this.
In general, any ideas are welcome.
Thank you!

For the first time I hear why you took it, perhaps it would be better if uCoz, albeit not at all serious, but even though its ecosystem is quite developed, they will help much sooner and more specifically.
This is not a problem, but what happens next if your site does not have PHP or another server-side language that can process HTTP payment confirmation from the payment system, notify the administrator about a new order, save any data to the database? In this case, new orders will simply come to your e-mail, the letter will be sent to you directly by the payment system, instead of confirmation via HTTP, and nothing more.
