Have a look at some of the other posts about a program called "Transmission". It goes what you ask for: Downloading of BT and a Web interface.
I'm currently testing it and I'm still not sure how I like it. So far it seems to be slower then Azureus on the desktop. Maybe this due to the maximum number of peers one can connect to or maybe the 400mhz processor is the limiting factor.
I hope you'll get it to work and have some good result with it.
