Why would you care if the software was written in Ada? It's not likely
any of the vendors would give you access to their source anyway.

It could probably do the task...

You probably wouldn't want to use a Canvas widget; Or at least, if you did,
you'd probably want to draw to a bitmap buffer and only use the canvas
functionality for selections and editing type work and possibly for dividing
up the frame for layouts. Trying to keep all that data + overhead in memory
would kill your program.

Good Luck. GIS's are fairly complex creatures. BTW: what "business analyst"
functionality are you looking for that commercial vendors are not providing?
