Two choices. Either you are now in phase starting to develop something 
totally new and special. Or alternatively you are totally beginner in 
writing simple Database application, using very common Data Controls.

To me that explanation looks like you should be able to read from your 
database some budgeting data, each record containing 12 fields. Then you 
show that data on your Form, in very traditional Excel type grid layout. 
User can edit the data, and then save it back to the database.

That is the expression that I get from your explanation. And the answer 
to write that functionality is to use standard TTable or TQuery 
component TDataSource and TDbGrid to show that data on Form.
User can easily view, browse and edit the data, and then you write it 
back to the database.

No need to start trying to understand anything about Object Orientation. 
Just write the simple code and finish your budgeting application.

For learning purposes, I quess you should also find much of the wanted 
OOP functionality and data reading/storing code, ready made, in the VCL 
source code of those controls mentioned above.
