I know nothing much about microcontrollers even i dont know how to programme a microcontroller perfectly but i have made lcd with out the help of any person just with the help of the HD44780 Datasheet. You should try this data sheet as it is just simplest
The majority of common LCD displays are based on the Hitachi HD44780 chip, so the interfacing is either 4-bit or 8-bit modes. Delays are critical when programming your particular MCU, the LCD will not function properly without them.
These examples should get you started in the right direction.
