How develop a financial software in Qt?

I want to c开发者_Go百科reate a little finance-software for my association. I want to keep it simple and easy-using, creating new persons should be possible, and every person has entries and costs. The programm should calculate the sum in every step and the total of every person.

Now my question: What is a good way to realize that? I thought about SQLite, which seems easy to realize, but not really perfect (f.e. no secondary keys).

SQLite is a totally good way to realize that.
You can have one table with names and a PersonalKey as PRIMARY KEY and another table with your bookings, where every booking has also a PersonalKey for the Person, the booking is for. So you can join the tables and make your SELECTions.
