How to store some settings without database but with sort of delete protection?

[Terreox]

Hi there
i would like to know if there is a good way to store some application settings? They have to be available even after restarting the program. So maybe i have to store an ID of something.
If i add 1 to ID (ID is 0) then i have to be able to get ID=1 after restarting the application.
I heard about QSettings but is it something that will suit my requirements?

Edit: If QSettings is the right way will all stored values be still available after copying the application to another pc?
