Looking for help with payment list

[Krawol]

I'm trying to make app for payment list. Could anyone help me with an idea how to solve something like this one:

When adding records I would need such items:

PAYMENT LIST Tables:

1. Month

2. Description

3. Amount

On first page I would like to have list of months with summary of all amounts.

When I click on specific month I would like to see all added payments with description and amount.

Would be really greatful for any advices.
