Ask IH: Can I build a HackerNews/DesginerNews for X with Webflow? (I am non-technical person)

Hello IH Nation, I am following this amazing community for a few months and it increased my appetite for starting a side project. I have an idea: a HackerNews/DesginerNews for a specific industry*.

As I am not a technical person but I still want to build it myself. I saw a lot going around here on IH threads that Webflow could be a suitable way to built it. I have set up 2-3 Wordpress sites, only installing plugins for some light features, but I think would be very hard for me (because of my tech gaps) to build this product in Wordpress with the following features*:

• a visitor can register for an account with little info (username, name, email, country) -> become an user
• an user can create a new item (thread/link)
• an user can comment on an item
• an user can like/unlike an item
• an user can view it's own activity/change password/change email etc
• multiple items categories
• each item have a score based on a formula (variables comments&likes&unlikes)
• home page will display the items based on items' score
• each user will have a score (karma) based on the score of his items & activity (comments on other people items)
• general leaderboard (based on users score)
• category leaderboard (based on users score in a specific category)

So... I can do it with Webflow? If not, what else would you recommend me? How long do you think would take me to built it?

I know I have a lot of questions, but I am pretty newbie in creating stuff in general. Thanks in advance for your answers!

• This industry consume a lot of content and they stay organized mainly in Facebook Groups & Twitter chats currently and I validated it. People want it.

** More features will stay for the moment in my had, I cannot articulate them in a understandable language.
