HI,
It will be difficult to implement serial interface, LCD controller and GPIOs in a CPLD, unless you pay a lot of money for it.

I would go for a small FPGA (like the Sptartan 3A starter board from AVNET that is about $49), this ywat you have everything you need, plus all the SW is freely available (ISE 11.3 can be downloaded from Xilinx web site).

Best regards,
/Farhad Abdolian
