As far as my experience goes, sqlite seems to use hardware-native formats, so that a x86-generated sqlite db would not work on an ARM target. That is, such an utility could be easily built to run on the tablet (where it would of course lose half the sex appeal of such a db builder, as you'd still have to transfer the full pack of files), but a PC-side db builder would be a big programming effort (effectively a cross-architecture backend rewrite).
