I would like to make some alterations to a widget I've found called "countdown timer"
it almost meets my needs but not enough.
so is there a resource that can teach me how to make alterations to it?
it is open source I assume?

Yes, it is. You probably want to look at something like http://techbase.kde.org/Development/Tut ... lasmoids_4
You will need to find out the files for this plasmoid, and then get and modify the source code and recompile it, as most plasmoids are binaries.
