I think Prima is defintely work a look, though it is relatively new. It seems to have a lot of nice features including a nice GUI designer, and works with both Win32 and X at least.

For reports, you can get a lot of bang for your buck using HTML, unless pagination is a serious issue, and PDFs could also be an option. I still use format and write a lot, with some limited font manipulation by inserting printer control codes in the output stream. Yes I am a walking anachronism ;-)

Please see also (GUI) Windows Programming FAQ and your local Super Search as GUIs and report generation do get discussed here fairly often.
