You might want to look at the portupgrade tool in the ports collection.
It supports a '-P' flag that tells it to use packages instead of
compiling from source. It does an excellent job of handling dependencies
(if used correctly), and is very easy to use.

It may be better to create a "friendly face" to using portupgrade,
rather than creating yet another tool that does the same thing. I am not
familiar with apt-get but I believe portupgrade would provide a solid
package management engine to whatever interface you choose to build
around it.
