Sure.  I can walk you though it.  Lets do it on the list (if you
don't mind) so that the conversation is available for others.

The xbase plugin is probably your best bet.  Its fairly old, so the
structure is a bit baroque, but it should cover the broad issues of
importing a database file.
Ok, I guess I set up everything to start. I already created a new
plugin directory 'paradox' and copied the files from xbase into it., and is modified. 

It looks like in the first step I must implement a function
paradox_file_open (GnmFileOpener const *fo, IOContext *io_context,
                 WorkbookView *wb_view, GsfInput *input)

xbase uses gsf to read the file. My library requires an open file
pointer. First problem: how do get a file pointer from the GsfInput


PS: Do I have to develop the plugin within the gnumeric cvs tree? Or
    is there a way to build it outside the tree?
