As much as I like Filemaker, it's capabilities are a bit overkill for what you are looking for. Might I suggest the Quickbooks? It is a simple to use and a quite robust program. And if you use Quicken, it will be an easy learning curve.
There are several flavors available, but basically,
it would be between the "Simple Start" or "Pro" versions. And if you can get your hands on the Student Price for the Pro, then you can get it for the same price as Simple Start.
