Is interraction between EditorWindow and php file possible?

Hi guys, (excuse my English)

Is it possible to interract with other a php file through WWWForm from an EditorWindow derived class ?

I tried to call a method of a monobehaviour script which calls the coroutine method performing the webrequest but it didnt work, any idea ? I could populate the database with a custom inspector using this very strategy but it didnt work with editorWindow :s

Thank you for reading, hope someone can help even a little :(
