If you mean 16-bit MS-DOS *.exe by "DOS *.exe", the answer is no.
If you mean 32-bit or 64-bit win32 console app, install the package
mingw64-x86_64-gcc-core-12.4.0-1 (64-bit)
or
mingw64-i686-gcc-core-12.4.0-1 (32-bit)
and compile with
mingw64-x86_64-gcc-core-12.4.0-1 (64-bit)
or
mingw64-i686-gcc-core-12.4.0-1 (32-bit)
