Creating a reminder system with a Form Plugin

Hello Everyone,

I am working on a project and I need some help and suggestion. I need to do some work involving users setting reminders. Users can login, go to the page create a Reminder Group and set reminders under the group, example – I create a reminder group titled “July” and I create reminders under July like “Visit Mr X” – Choose date and Save, “Buy Y” – Choose Date and Save. Once I login, I can see only the reminders I saved and can add more Reminder groups or single reminders under each group.

I am considering the possibility of using a form plugin for this. Is there any form plugin (free or paid) that can create something like this.

I will appreciate feedbacks and suggestions.

Thanks
