how to create a form attached to a table

Hello,
Once again I am looking for your precious help,
What I am looking to do is having an easy way to create an event, looking for the details of it and edit info as we getting ready to it.
I attached an excel file to give you a clear idea of what I am looking to do. (this is mostly what i would like it to looks like)
This is just part of it and more info will be included but I just need to get to learn how to do it.

My sheet is compose in 3 part.
A Table with all the event and info.
A edit and new event form to edit the info in the table and create new one
A little event calendar on the left.

I may be to demanding but I learned that everything is possible on excel.
Can you help me?
Thank you in advance.
