Help with C#.net and Sharepoint 2003 development

hi! is there anyone here who had already developed or into developing a windows application using c#.net that is capable of talking with sharepoint Portal 2003? if your the guy can you please help me...im new to c#.net and im planning to develop a windows application that work with sharepoint portal 2003. But, im not sure if i have all the resources or requirements needed in order for me to develop a windows application. What i have now installed in my pc is a Visual Studio 2005 (C#.net) .NET version 2 and the sharepoint portal 2003 is installed in different box.Basically, the windows application that i would like to develop is a application that would get data/information from specific calendar in sharepoint 2003 like the Name of the Event,date,location, etc. My question is, is/are there something i forgot or something do i need to do before i begin into developing application together with sharepoint 2003? is it posible to develop a windows application that works with sharepoint 2003 into a box where sharepoint 2003 is not installed? Thanks in advance!

Indeed it is - SharePoint has several web services (as the object model isn't remotable): the one you're looking for is located at http://<server>/_vti_bin/Lists.asmx.
