C# App, Data Submit to sharepoint list

 Hello,

I have created a simple C# application in Visual C# 2008 Express edition.
The application contains a drop down combolist box containing needed data.
A numbers only text field that will contain needed data
an animated gif
and a button.


The results of the application i would like on click to send the data to a sharepoint list site without overwriting data simply adding it to the list.

Is this something that I can do within the language and if so can anyone offer me some assistance with this?  




Thanks
