If you want quickbooks for GNU\Linux I urge you too look at GNUCash
(http://www.gnucash.org)

Originally we were going to write financials in XUL.  The problem is they
at the time and probably still do not handle external data very well.
They require basically XML datasources.  This is what prompted us to write
data aware XML markup for XPlatform forms with GNU Etnerprise.  You might
wisht to check it out http://www.gnue.org.  All forms are done in XML like
XUL, but you need to know no SQL or databinding to make data ware it
'automagically' binds for you.

BTW: Unless MySQL has fixed table level locking you DO NOT want to use
MySQL for financial applications.  Table level locking will KILL you even
in a small environment.  As any time your run complex reports you in
essence will be locking out your data entry team. Performance will be
horrible unless you do some replication scheme to make a reporting
'server'.

GNU Enterprise does this.  Currently we support Oracle, DB2, PostGRES and
MySQL.

This is concept of GNU Enterprise as well.  One form source will work on
Win32, Motif, GTK, Mac and soon WWW with no ifdefs etc..

BTW: Mozilla's XUL went down hill around M10 when Mike Shaver departed and
Dave Hyatt seemed to be less involved with data binding.  Most
unfortunate.  Plus the code was still so impossible to compile much less
code against at that time, we decided XUL wasnt best for us.

In its defense its still cool if you are wanting to just do XML data
sources.
