Well, it's pretty easy in Sed:
ifconfig | sed -n '/HWaddr/{N;s/^\([^ ]*\).*inet addr:\([^ ]*\).*/\1: \2/p}'
Or if you want your loopback too, you can use
ifconfig | sed -n '/Link encap/{N;s/^\([^ ]*\).*inet addr:\([^ ]*\).*/\1: \2/p}'
These can be shortened a bit as "Link encap" can be just "Link" (or even "Li") and you don't really ned the whole "inet addr:" bit, when "addr:" or even "r:" would do.
Making a final sedlet:
ifconfig | sed -n '/HW/{N;s/^\([^ ]*\).*r:\([^ ]*\).*/\1: \2/p}'
or
ifconfig | sed -n '/Li/{N;s/^\([^ ]*\).*r:\([^ ]*\).*/\1: \2/p}'
