No, the natural numbers aren't a language structure. A language
structure looks like this:

<a set U, family of relations of various arities on U, family of
functions of various arities on U, distinguished elements of U>.

The details will depend on the language. U may be the set of natural
numbers, indeed (for first order languages) it can always be chosen to
be N so long as it isn't finite. But that has got nothing to do with
your false claim that G\"odel's incompleteness theorem relates to
language structure.

When a true genius appears in the world, you may know him by
this sign, that the dunces are all in confederacy against him.
