That certainly is a very interesting question.

And the answer is that components generally aren't particularly reusable,
as they tend to be too tightly integrated with each other. Components are
for making plugins to frameworks, and hence you can use a component
architecture when you build a framework. (Zope3 tried building the
framework OF components, but that IMO proved to be too complex).

Reusability comes in the forms of libraries, services and frameworks.
Hence, in your case, as you are building a new web site, you need a good
website framework. There are many good Python web framework to choose
between to get things done quickly. ZTK is not one of those. Neither in my
opinion is Grok, which was a valiable attempt to make Zope 3 development
less complex.
