I thought the OP _was_ referring to constructing a syntax script, which
is indeed a kind of programming and would IMHO not benefit at all from a
menu-driven interface.

However, if the matter is merely choosing among the existing "known"
filetypes, then there _is_ a menu, however you must first enable it by
using "Syntax => Show filetypes in menu". Then you get a menu for
setting the 'syntax' option. Experiment shows that it also sets the
filetype, e.g., after you've added the filetypes to the Syntax menu,
clicking "Syntax => A => Aap" sets both 'filetype' and 'syntax' to "aap".

In Console Vim, it is possible to use the same menus as in gvim,
provided that your Console Vim is compiled with +menu. They look
slightly different because of the differences between a text interface
and a GUI; and they are at bottom rather than at top. See ":help
console-menus" about how to enable them in your vimrc.

I agree that automatic setting of filetypes is the Vim-like way to go.
Some filetypes are so similar that user guidance (I mean, guidance
_from_ the user _to_ filetype.vim) can help discriminate among them.
This can be done either by means of global options, or of modelines,
depending on the particular circumstances. For details, see:
:help filetype.txt
:help syntax.txt

Best regards,
Tony.
