You can get it easily via gitbash (https://gitforwindows.org), or WSL, or cygwin or ... dunno.
You can also try compiling it for windows directly. Nano provides some Win32-specific stuff on its website (https://www.nano-editor.org/dist/win32-support/), but I haven't tried them, since nano through gitbash worked fine whenever I've needed it.
