LCD Based cycle timer?

So basically I’m in need of a cycle timer like this one (CanaKit but instead of just buying that one I wanted to use an arduino with an LCD to do do the work.

I’ve got an arduino UNO R3 (I think it’s R3) and I picked up this keypad LCD display today in the hopes that it will allow me to do what I want.

What I want to do is use this to create a cycle timer that will let me adjust the cycle times (On/Off length) on the fly by using the LCD instead of having to change code, reupload and reset the arduino.

I have a pretty good understanding of electronics as an electromechanical engineering technician, but my programming skills are plan and simply crap.

Is there anyone out there who would like to help me out with this little project?
