sory, but isnt this a question to be answered not shuned off? tis no good telling people that its a big project that takes months to do, how would some one go about doing it IF they had months to spend???
Learning either C or C++ enough to make a browser: 6, 7 years
Learning every specification with regards to the web (HTTP, HTML, JS, etc): 1, 2 years
Coding your HTML parser according to the specs, with different modes for HTML4, 5, and their tolerance levels: 1, 2 years
Coding your own JS engine that doesn't suck: 2, 3 years and lots, LOTS of studying
That's about... 40% of the time.
No, you won't be able to do it yourself. I'm sorry if this brings you down - it's not a project to be taken by a single person. It has an enormous complexity.
