Developing a wizard form builder

Hi friends
I need just a little bit of help with developing a plugin.
I don’t know how to start it.
I want to develop a plugin that users could somewhat drag it into page or post content(of course this step occurs from admin panel), the form maybe would have some initial selected values when customers see it on the client-side.
On the customer side, when a user selects an item for example from a dropdown list in the form, I must handle dynamic data loading via Ajax so that the user could go to the next step on the wizard form and so on till submitting the form.

What I tried until now is creating a wizard form using WordPress Widgets but at the Widgets just could be added into the footer or sidebar and not in the content of the page or anywhere user want.

I wonder if there is any solution so that I could extend for example WordPress Visual Editor so that users could drag the form into what content they want to publish and config the form.

I appreciate it if anyone gives me a clue on how to start.
I’m a PHP(Laravel) developer and I can technically handle what I want to do, but have no idea from where to start.
Thank you in advance.
