Maxim makes a couple of IC's you will find convenient to build your battery charger arround. You will need to specify a couple of components, but if you use there suggested circuit and provide the suggested voltage and power requirements, it will work fine, and I have packaged the circuit very compactly before.

The MAX712/713 can be found at:
