In most cases, there are calendars and other objects in the gallery meant for use as templates. You just change out for your own graphics so that the script is all you're using. Be sure to credit the scripter.
sViz has several templates in her gallery, such as weather, clocks, etc.
PM me, sViz, or post here in the forums for more help.
There are tutorials in the forums also. Look here: DesktopX Tutorials
I'll be glad to help with anything I can.
