Can i make a social media site with limited programming skills?

You need to secure the site and keep user records. That requires a database, usually mysql as the standard. That requires learning php to manipulate the data and read it back to build the html for the displayed pages. Before you even start you need to study data validation and security of data entry. Get that wrong an a hacker can use a VERY small piece of code in a user name or password field to allow access to the site with NO password. ANY entry field can also be used to insert a link to a script which also allows them access. Ether way they will have FULL access to eh site including the site database user account. This can result in your site being taken over in a week, and running illegal background activity like bank phishing scams or child porn distribution. And you would no know until the authorities come after you.
