Create a WordPress plugin

I need a custom Wordpress plugin that loads my webpage on the WordPress Admin view and installs the free, open-source extensions from GitHub and other repos that are listed on my webpage. See the screenshots for details.

NOTE: Your message\proposal must begin with "ABC" for me to consider your proposal. Otherwise, I will assume that you are a bot or have auto-reply.

Skills Required: WordPress Plugin Development, PHP & JavaScript.

Thank you!
