Err, it isn't quite that simple.

The malting process does convert some starches to sugars, but most
importantly, it creates those enzymes that can finish the conversion in
your mash tun.

Now those enzymes are not all that specific, they can convert other
starches as well as their own. So, a reasonable amount of almost any
grain (rice, corn (maizena!), rye, wheat, unmalted barley, you name it)
will get converted to sugars, and from there to alcohol.

Of course, the enzymes must be there, so attempting to brew a beer from
maizena and unmalted rye will not produce much of anything fermentable.

Modern malts are so well malted, that you can mix malted barley with
extra starches almost 50-50! 

What adjuncts to use, and how much, depends on two main criteria: For
the commercial mass-volume discount breweries it is mostly a matter of
price. For us connoiserus of home brew, the crucial factor is what other
flavours and nyances do those things add. Rice and corn give relatively
little taste, and can be used to lighten up a beer that is getting
overly heavy, whereas wheat produces a wheat beer, as we all know. Rye
is said to add dry crispiness to the beer, and oats add some body,
mouthfeel, and head retention (and stuck mashes).
