Here's a little bash script I call sendcmd to do what you want:

#!/bin/bash

# usage: sendcmd -c "echo hello world" -w 0,1,3

WINDOWS=0
CMD=""

while getopts 'c:w:' OPT; do
    case $OPT in
        c) CMD=$OPTARG;;
        w) WINDOWS=$(echo $OPTARG | sed 's/,/ /g');;
    esac
done

# Use the first screen found
STY=$(screen -list | grep pts | head -1 | sed -e 's/^\s//' -e 's/\s.*$//')

for WIN in $WINDOWS; do
    STY=$STY screen -X at $WIN stuff "$CMD\n"
done
