actually, i'm trying to build such a thing myself.
with python + QT.
the main problem i face is memory consumption:
python + qt + small-gui-app = consume most of the free memory on the machine( slc-860!), i.e., 50-60% ram, which is WAY too much if you like to multi-process.

maybe i'm doing something wrong.
i'll try to post the code somewhere. in the mean time, if you want my source-codes (it's far from being operational) - just contact me.

(i know there's "portabase", which aims to do something very similiar.
however, i find it too buggy (import/export/crashes),
not enough user-friendly for my needs,
not using a standard DB format / not using SQL db access.
i feel restricted with that tool)

I've seen this today, seems related to what you want:

But we don't have wxWindows on the Zaurus, or did I miss something ?...

well, the signature says pdaxrom, where using vxWindows is possible.

Oh right, sorry. Not sure the memory problem will get any better though...

certainly better than Gnumeric memory.
anyway gnumeric works surprisingly better than handicapsheet, so for now i will stay in pdaxrom.


thanx
