XML editor

Hello !

I'm searching for a Xml Editor for user. I mean, , I want to
know if a tool exists, able to design a window with textfield, combo box, etc... according to its Xml schema.
Typically, if on the Xml Schema, an element is a choice item, the window form should create a combo box with the different choices specified in the Xml schema.
Then after filling the gap required, the program creates the Xml file with data provided by the user in the window editor.

The langage used by the program could be C++ with MFC or Java.
Thanks for your answer.

Sorry for my bad english, I'm french !
