Charge control circuit

[newbs]

I need to build a charge control circuit for a battery powered LED fixture;
input: 6vdc .300mA
to charge 4 NiMH AA batteries.
I would like an LED to indicate charging/ charging complete.

I understand schematics and electrical componants and am experienced in soldiering, but have no electrical design training.

I've found a ton of schematics for solar charging applications, but don't know if they apply, or how to tinker with them to work for an outlet adapter.

HELP!!!???!!!??!!?
any resources I have overlooked?
could I pull the circuit out of an old radio or cordless phone? how could I distinguish the charge control circuit from all the other circuitry?
