By using the standard Delphi controls and components, you can write 
applications and also Database Applications without knowing very deeply 
about the OOP lying behind there.

I think this has been the whole idea in 'modern' application development 
at least 10 years or more. Use such 'simple' development tools that you 
can hire cheaper and more easily available developers.

The background data for this specific budgeting problem has been given 
and described in the opening message.
I do not see there _anything coming even close_ to that point that the 
functionality of Data aware controls could not solve it.

If they would not, then you would need to start digging in to VCL code, 
and see what kind of enhancements you would need to write there.

Yet, for _DB Application Developer_, it usually is always the more 
expensive and slower alternative 'doing it yourself'. You seldom need 
need to start writing massive amounts of VCL code just to build your own 
enhanced Components and Controls.

The cheaper alternative is almost always already available on the 
market. Buy some third party tools and controls, and you'll get your 
problem solved within the budget and time scale.
