Agree with this point. It depends on your skills and on the needed site type. But anyway it’s a hard labor and developers spent a lot of time learning and practicing before they start to make sites of high quality.
There are many CMS tool is used for website design. But which tool to used for make a websites its depend on what kind of facilities you want in your website. Normally Wordpress is most useful to create a website. But you want an E Commerce website so you go with Magento. It provides more security then wordpress.
I will say you start the designing and html part development, after that you decide which programming language you want to use. As are about to develop a personal site so there is no hard and fast rule you need to maintain. Give it a kick start the remaining will come with time.
