How to Create a Learning Management Plugin in Wordpress to Manage Courses [LMS]

I'm looking to build a small learning management plugin to manage courses

The first feature that i want to implement is the front-end course builder Meaning that after designing a course page (using it as a default canvas)

This course builder will do the following:

[Button] -> Create new Course - Add Course title: - Add Course Picture: - Add Sections: - Add Lectures: [Button] -> Publish Course

After hitting 'Publish' a course page will be created automatically and added to the database

Any help, tips, assistannce will be greatly appreciated.. I'm stuck for several weeks now
