I may wish to possess the Content management systems abilities (or at best the fundamental benefits like CRUD) for my custom db table. It is possible to method of doing this. Migration isn't a choice for me personally since you will find other programs which use this table.
Any help could be appreciated. :)
Two options come to mind for rapidly build 'basic' components for example you describe here.
JFooBar component - is an element you put in into Joomla 1.7 that facilitates building components that you simply then package up: https://github.com/Niambie/jfoobar
Alternatively there's a web-based tool that does an identical job: http://www.j-cook.pro
I have only performed with one of these tools - but have a few projects that require something simple knocking together and will also be giving them a shot on 'real world' projects shortly.
