Took a quick look. You can easily create a dcv connection bookmark file (this is on Mac OS). The contents look like this:
[connect]
host=*host*
port=8443
user=*user*
password=*pass*
weburlpath=
[version]
format=1.0
…save it as something_maningful.dcv and then double click and it connects directly. If you don’t want a password in there just remove that line and the users prompted for the pass.
