If what you want is a nice, standalone piece of code you can extract to
duplicate the functionality of, say, the first grid demo (the one with
cities in European countries), it's not simple to do this. However, it's
not exceedingly difficult either. In addition to looking at the wiki as Ric
suggests, you can start the demo in a J session, then move into the demo
namespace to look at the items there.
For instance, in your J session after you've started the demo and brought up
the cities grid example, you can do this to move to the locale, look at the
variable names, and look at the "definition" for that example (however, you
still need to figure out which code to copy to set up the form and all):

end.
()
CELLDATA=: sumdata ?. 10 12$1500
CELLFMT=: 'c'
CELLEDIT=: ((10 12$1),0),.0
NB. Look at the numbers in the active grid:
$CELLDATA__grid
11 13
3 3{.CELLDATA__grid
1146 755 1079
1213 1318 151
864 671 1213
NB. Change the numbers:
3 3{.CELLDATA__grid=: (99.9) ({2$<i.2)}CELLDATA__grid
99.9 99.9 1079
99.9 99.9 151
864 671 1213
NB. Now do something in the grid like "Zoom Out" or "Flip" to force
re-display to show the data changes.
NB. I haven't figured out what you have to do programmatically to
re-display.
