Friendly UI to alter webcore variables?

Apologies if this is asking a little too much, but I can't code to save my life.

I'm looking for some guidance to allow me to essentially scroll down a page of times (i.e. day by hour), and alter the associated temperature (or variable) using am up/down arrow or the like.



TIME                TEMP
0000-0001    6                       [up arrow] [down arrow] [save]
0100-0200    8                       [up arrow] [down arrow] [save]
