Something like that. I agree too that that's not the best way - in fact 
I'd already changed it that for Windows, when you click "Create location 
using projection values" it pops up a terminal window to run etc/set_data. 
It's not just g.setproj - etc/set_data also forces the user to set 
the initial region and in general does a bit more (I'm not 100% sure what 
else, but creating the projection files and setting the initial region are 
the main things).

I would like it though that we could just run g.setproj and return to 
gis_set.tcl - as it's a bit confusing running set_data - after creating 
the location you have to press Ctrl-C to exit back out.

If we can design a GUI widget to force the user to verify/set the initial 
region after creating a new location, then this could be presented after 
the 3 different methods of creating a new location. And then we could 
simplify the "using projection values" button to running g.setproj in a 
pop-up xterm Window and do the region setting through the GUI afterwards.

I have committed Maris's patch now, with this extra modification. The 
thing is, you still need to press Ctrl-C to exit out of it after creating 
the new location. And that isn't obvious. But, like I said, once we can do 
the initial region setting in the GUI, then we can simplify that.
