To make it a little easier for myself, I threw together a zenity script
to help setting the parameters. I left off the DHCP part as I wanted to
to do this manually.

#!/bin/sh

# Script provides a gui for connecting to an 802.11 wireless access point

defaultap=
TMP=/tmp/apscan.tmp$$

# the wireless interface can be specified on the command line
if [ -z "$1" ]; then
    int=`zenity --entry --title="Interface" \
    --text="Enter wireless interface name (e.g. ath0)"`
    if [ -z "$int" ]; then
	exit 1
    fi
else
    int=$1
fi

# see if the Operating system knows about this interface
temp=`netstat -i -I $int|grep $int`
if [ -z "$temp" ]; then
    zenity --error --title="No Interface" \
    --text="The interface $int is not installed"
    exit 1
fi

# subroutien to clean up before exit
cleanupexit() {
    rm -f $TMP
    exit $1
}

rm -f $TMP
