Keypad logger project help

Hello everyone,
I am working on a keypad logger DIY project which is quite simple to someone with experience, but for a newbie without any experience like me, it's a hugh task, so I hope someone can help me out a little bit.
The target of the project is like this:
Make a stand-alone 4x4 keypad with battery and circuit which can record the every keystroke on the keypad and with time stamp. The data will then be transfered to computer after certain amount of data has been recorded. The connection method can be usb, rs232 etc. Also the circuit board is expected to be as small as possible to fit in the keypad casing.
I did a lot of research on the web about similar projects, based on my research, I think there is some possible approach:
1, Single Basic Stamp chip
2, Basic Stamp + extra eeprom memory
3, Keypad encorder suchs EED1144 + Basic Stamp
4, Keypad encoder + Atmel· 89C20XX Chip + eeprom.
5, etc.
Here is some similar projects that I've found over the internet,

I don't have any electronic experience, but I am willing to learn, so can anyone tell me which approach is best for me to finish the project within relatively reasonable time period? Will it take too long to learn all the stuff needed?
My email is c507s@yahoo.com
Thanks a lot in advance.
