You can download the "Annotation CSV" (or other format) for your chip from
"http://www.affymetrix.com/analysis/download_center.affx". The file contains
mappings to GenBank accession numbers, Unigene ids, and other information.

AnnBuilder is for building annotation data packages. It does not have the
function of keeping track of the history of cloneIDs.

AnnBuilder does not have built in parsers to parse data from I.M.A.G.E. However,
you may write your own parser to parse the data from I.M.A.G.E or other sources
using AnnBuilder. Have a look at the parsers in the "data" directory for the
release verion or "scripts" directory for the developmental version of
AnnBuilder for exmaples of parsers.

Yes, you can use AnnBuilder to build an annotation data package like those
available from the Bioconductor web site.

AnnBuilder also generates XML files containing annotation data. You may try to
parse the XML files and dump the data into a database.

No, AnnBuilder does not do that.

R has a tcltk package for building GUI interfaces.
http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ has examples of
constructing common widgets using R. Bioconductor's widgetTools and tkWidgets
packages also have exmaples and widgets built using R tcltk.
