[root@atlantis ~]# cat generateKickstartConfig.sh

Code:
#!/bin/sh

#define outputfile
KS_CONFIG=ks.cfg

echo -e "Starting Kickstart Configuration Generator Script ...\n"

echo -en "\tWhat is the IP Address:"
read IP_ADDRESS

echo -en "\tWhat is the gateway Address:"
read GATEWAY_ADDRESS

echo -en "\tWhat is the DNS Server:" 
read DNS_SERVER

echo -en "\tWhat is the Hostname:"
read HOSTNAME

echo "network --device eth0 --bootproto static --ip ${IP_ADDRESS} --netmask 255.255.255.0 --gateway ${GATEWAY_ADDRESS} --nameserver ${DNS_SERVER} --hostname ${HOSTNAME}" >> ${KS_CONFIG}

Remember to make the script executable
Execute with ./generateKickstartConfig.sh
Answer the 4 questions and "ls" your directory, you'll see a ks.cfg file

This is a very basic solution, there's so many possiblities, you can verify the user input to check to see if the values are valid, like if they enter an IP for hostname or vice versa, check DNS to see if these IPs resolve before using them in the kickstart, use regular expression to verify the user input, if its invalid you can loop to verify they enter something useful, I mean you can write a pretty complicated script to generate your ks.cfg file.
