I don't know about any global VFR WPT database, don't think it could even exist such thing (Jeppesen maybe?). Anyway that info is at each country AIP, it would be nice for users to enter that info on your program, just name and coordinates. Or I can collect all info (Spain, maybe others like Portugal or France) in any convenient format for you.
I've inserted the Slovene VFR waypoints manually from the Jeppesen VFR chart and AIPs. We have about 30 of them if remember well so it wasn't a hard work.
Is there a way to export them from the application? Otherwise can re-enter them in Google earth and make a .kmz file.
Maybe other users can make the same for own countries...
