Could i build my own webpages and applications with just the basics of python?

This essentially more of a philosophical question than a coding question. And if I am understanding your question correctly, what you are really asking is can a website be coded in Python without using a framework? And the answer is 'yes', theoretically, using vanilla python, but the real question is whether or not it is a recommended approach.

One comment on Stack Overflow was this (regarding making a webpage in Python without a framework):

The answer is "don't". Using a framework makes your code more
maintainable, scalable, readable, testable, and modular.

And an answer on Quora was:

Yes, quite easily.

You could use a web server like Apache, and use Python for your 
CGI scripts, quite an old fashioned way to do it these days, 
but it still works fine, quite easy too.

If you don’t want to use a web server, you could write your
own in Python, it’s not as hard as it sounds, open up a socket
on port 80 and start listening… I wouldn’t recommend this though, 
if you don’t know what you are doing,
you’re going to have security holes up the wazoo…

I'm led to believe that this is a recommended framework to get started with, though, because (another Stack Overflow quote), "You should try web.py, it provides a bare minimum of features that does not get in your way.":

http://webpy.org/

Also, have you explored Flask or Django?

For more info, just Google "Python website without a framework".

I hope that helps. Happy coding.
