Binding a drop-down list to a SharePoint list

Has anyone achieved the above successfully and could run through the steps, or point me to a how-to guide?

I want to display a list of items from the SharePoint list and allow the user to select one.

I'm using SharePoint 2010 and suspect that consuming the SOAP web service (http://dur-xxxx-02:12345/_vti_bin/Lists.asmx?wsdl) from a WSDL data source in LiveCycle Designer is the way forward, but can't get it hooked up properly.

Eventually I want to create a new list item using the values that the user has entered, so if anyone has a guide on how to do that, I'd appreciate it, too!

Thanks for any help.
