I see no reason you couldn't connect mobile internet to a home pc. (presumably "dongle" is mobile 'net? I sure hope so anyway....)
Any half-decent computer shop should be able to get you sorted pretty quickly.
I'd say it's certainly worth a go.
Especially given the alternative of severe WGT withdrawal ("intense pain, profuse sweating, difficulty in breathing, loss of consciousness, violent convulsions, and finally....death" - A. Cooper).
Never a pretty sight....
