As to this part of your question.. I don't personally know of any applets 
exactly.. and kismet is more for finding wireless networks you aren't suppose 
to find, and logging them all (Oh man, that list goes on.. kismet does so much 
more, but has nothing to do with my answer for you.. so i wont get into it)

iwlist wlan0 scan

This will give you everything it can see, what their SSID's are, what their 
mode is, bit rates offered, quality/signal/noise, operating channel, and of 
course MAC address.

This command also works even under NDIS wrapper if you're using 802.11g with 
windows drivers on linux.
