2) I want to keep the current date on the screen (and time as well, but

   Is there a smart way to have a button periodically refresh its

thanks to the previous hint to SendToModule ... ChangeButton my solution is to run via crontab at midnight the following two line shell script

set a = `date "+%a %b %d"`
/usr/bin/FvwmCommand "SendToModule MyBox ChangeButton myDate Title '$a[1] $a[2] $a[3]'"
