How can I auto upload a file to the server?

I have a .txt file on my local Windows 2000 box that i want uploaded to a remote L.A.M.P. server with only one click. I want to have a link (shortcut) on my desktop when clicked it launches a web browser loaded with a remote .php script that automatically goes into C:\data\upload_me.txt and uploads "upload_me.txt" I know how to upload files using php with a "browse to file" html form, but i want to skip the form and have the file just upload automatically when the script is loaded. I don't know how to make the .php script automatically grab the file from my local box and upload it without any user intervention. Any suggestions? Thanks for you help, cheyrl.
