You really, really want to just get an LCD module with a controller built into it. Then you can just do read/write instructions to the display.
Everybody asks about how to use these junk controller-less LCDs. It's simply not practical, I've never heard of anybody ever doing it. A microcontroller would have a really, really hard time, you'd spend more $ and far more time than just doing the module. But like I say I've never even heard of someone getting it to work.
