Hi Charles,

I wonder why you want to develop a Jabber client without using any 
existing library or client. If you really want to start from scratch, 
Jabber is one the easiest IM protocol available for implementation.

I think you could start first from choosing an XML parser, as Jabber is 
based on XML. Then you could start to learn the protocol by trying some 
existing Jabber clients. Most of them could reveal the actual underlying 
XML data that are sent. Then you could look at the Jabber protocol 
itself, http://www.jabber.org/protocol/, especially the two IETF 
internet drafts, http://www.jabber.org/ietf/.
