When you say "copy a file" do you mean you want to copy one specific file one time or do you mean you have a reoccurring need to copy files?
Using scp is almost always the best option. It's secure, it's reliable and since you probably already have ssh set up, you probably don't need to set anything up that isn't already set up. If copying to/from windows you need to initiate the scp connection from an scp client (PuTTY is great) on the windows box for the no-need-to-set-anything-up claim to be true.
If you're trying to set up a regular automated copy, scp is still #1. You need to read up on using ssh keys for authentication. (Again the PuTTY manual is a good starting point if you're working from a windows perspective)
Other alternatives include putting the file on a web server, ftp server, smb server etc... but the conditions in which one of those would be better than scp are few. Could you tell us a little about why you don't want to use scp? Scp is the secure successor to rcp which is the remote version of cp, so I really think scp is what you want.

scp(1) User Commands scp(1)
NAME
scp - secure copy (remote file copy program)
SYNOPSIS
scp [-pqrvBC46] [-F ssh_config] [-S program] [-P port] [-c cipher] [-i identity_file] [-o ssh_option] [ [user@]host1:]file1 [...] [
[user@]host2:]file2
DESCRIPTION
The scp utility copies files between hosts on a network. It uses ssh(1) for data transfer, and uses the same authentication and provides
the same security as ssh(1). Unlike rcp(1), scp will ask for passwords or passphrases if they are needed for authentication.
Any file name may contain a host and user specification to indicate that the file is to be copied to/from that host. Copies between two
remote hosts are permitted.
OPTIONS
The following options are supported:
-4 Forces scp to use IPv4 addresses only.
-6 Forces scp to use IPv6 addresses only.
-B Selects batch mode. (Prevents asking for passwords or passphrases.)
-c cipher Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1).
-C Compression enable. Passes the -C flag to ssh(1) to enable compression.
-F ssh_config Specifies an alternative per-user configuration file for ssh(1.).
-i identity_file Selects the file from which the identity (private key) for RSA authentication is read. This option is directly
passed to ssh(1).
-o ssh_option The given option is directly passed to ssh(1).
-p Preserves modification times, access times, and modes from the original file.
-P port Specifies the port to connect to on the remote host. Notice that this option is written with a capital `P', because
-p is already reserved for preserving the times and modes of the file in rcp(1).
-q Disables the progress meter.
-r Recursively copies entire directories.
-S program Specifies the name of the program to use for the encrypted connection. The program must understand ssh(1) options.
-v Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging
connection, authentication, and configuration problems.
OPERANDS
The following operands are supported:
host1, host2,...The name(s) of the host from or to which the file is to be copied.
file1, file2,...The file(s) to be copied.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred.
