On KIT059, P0_2, P0_3, P0_4, are each connected to 1uF capacitor for reference voltages.
You'll need to de-solder these capacitors if you want to use Port 0 for LCD.
Also, be aware of the other connections for Port 12 on KIT059:
P12_6, P12_7, UART connections to Kitprog.
P12_0, P12_1, I2C connections to Kitprog.
These connections do not appear to be affecting your LCD interface. But in the future, you may wish to use USB-UART bridge that Kitprog offers and this would interfere with LCD interface.
Good luck with your project.
