I don't think there is an interface to the 'parse tree of the html page' via 
docp.

I don't think you can do that with just the 'dcop' command line utility and 
kdialog, but you don't need to write in C++ either. There are some examples 
of using a KHTMLPart from python and ruby in kdebindings, see:

python/pykde/examples/pyKHTMLPart.py

korundum/rubylib/examples/rbKHTMLPart.rb
korundum/rubylib/examples/RubberDoc.rb
korundum/rubylib/examples/kludgeror.rb

Then you cold write your own 'custom konqueror' to access the homebanking 
website. The RubberDoc.rb example has code to walk round the DOM tree, which 
is the closest thing to your request about needing to access the html parse 
tree. But I'm not sure if there is an interface to KHTMLPart that allows you 
to programmatically fill out text fields though.
