Writing a GUI - Where to start?

Glad that it was usefull. Meanwhile HPDF is outdated (still on FFI, a port to NativeBoost would now be state of the art) and we also have Artefact for PDF generation as a "Pharo only" solution. One question: did you "hard code" the PDF layouts for the documents in the "lawsuitTracker" or what did you use to (quickly) define the report layouts? I would like to see some kind of general reporting engine in the future. Either a pharo based one or by using templates from existing engines (for instance JasperReports has a nice visual ui designer and layout templates are stored in XML files) With a future UIBuilder for PharoUI's, Seaside for Web-UI's and a (Pharo based) ReportingEngine Pharo could be an attractive solution to build business software... Thx T.
