In bash or whatever shell scripting :
- to read passwords from a txt file: yes it's possible (while read..)
- to try to connect to a wireless connection: yes it's possible (bring up eth n )

To connect to a wlan net:

iwconfig wlan0 essid NETWORK_ID key WIRELESS_KEY

If the key isn't hex, but ascii:

iwconfig wlan0 essid NETWORK_ID key s:WIRELESS_KEY
