rysnc is a very powerful alternative to cp. It provides basic things like you want here, progress meters, copying to remote sites, a diff algorithm to efficiently maintain mirrors, compression, etc.
I think you want something like this:
rsync -r --exclude=.svn /home/user/progname/ /home/user/progname.copy
I almost always use -a (archive) instead of -r (recursive) because it means -r and more (see the man page). The trailing / on progname means `contents of' (otherwise progname.copy will contain progname and everything will be one more level down). Put a trailing / on .svn to only exlude directories with that name, instead of both directories and files with that name, if for some reason you had files named .svn that you wanted to keep in the copy.
rsync is awesome
