$ file `which xhere`
/usr/bin/xhere: Bourne-Again shell script, ASCII text executable
$ head `which xhere`
#!/bin/bash
# Have to use bash; can't get ash to "exec -l"
# Separate script from chere to avoid need for argument parsing
#
# first arg is shell
# second arg is the path
...

Can't do that: xhere expects shell path /bin/*sh* and directory path and 
runs under bash so it can run exec -l to exec shell as login shell after 
cd dir.

Starting XWin Server from a shortcut uses:

C:\...\cygwin...\bin\run.exe --quote /bin/bash -l -c "cd; exec 
/bin/startxwin"

so you could base a commnad line on that.

You could also install and use Cygwin-X with a GUI file manager like 
PcManFM, or a text version like Midnight Commander (package mc).
