Tom,

If you want to play around with TclTk a bit, you could simply add a line or
two in one of the currently existing menus (all in
$GISBASE/etc/gm/gmmenu.tcl) to do a specific task. For example, you could
add a menu entry that could have for its command: "v.surf.bspline
input=wstation_temp raster=tempmap type=bicubic column=temp"

This would take a file of vector weather station points named
"wstation_temp", with an attribute column named "temp", and use bicubic
interpolation to create a temperature surface named "tempmap"

Here is a bit of script that could be inserted into the raster menu to add a
submenu for doing weather-related raster modeling

{separator}
{cascad {[G_msg "Weather modeling"]} {} "" $tmenu {
   {command {[G_msg "temperature surface"]} {} "bicubic interpolation
           of weather station temperature data" {} -command {execute
           v.surf.bspline input=wstation_temp raster=tempmap type=bicubic
           column=temp }}
   {separator}
   {command {[G_msg "another menu entry"]} {} "put the help text here" {}
           -command {execute GRASSCOMMAND }}
}}

{separator} inserts a line separating menu items
{cascad... } creates a submenu
{command...} creates a menu entry that starts a command.

Maybe this can help you show how easy it is to make custom menu entries.
Hope this is helpful.

Michael
