Looking for a way in SharePoint 2007 to create a page that interacts with a web service

My situation is this. I use a couple of vendor application that provide a multitude of web service methods.

I would like to be able to invoke some of those web service methods to perform work.

One such piece of work is to unregister a user (ie delete them from the database).
To do that, I have doc from the vendor about the web service method and how all it needs is to be sent a login.

I have a long list of logins that I would like to delete.

So, in an ideal situation, I would like to figure out some simple way to take a text file or SharePoint list of logins, feed them one at a time to the web service, so that the users would be deleted.

One gotcha is that I don't program in VisualBasic or C# or Java. I have written code in Tcl, Perl, and a variety of command line scripting languages. And I've fiddled a bit with building SharePoint pages with various web parts.

Is this something that is doable without learning a new programming language?
