To get 3d position where you clicked you can create camera to viewport ray and then check intersection with terrain or other objects:
MyGUI::IntPoint mousePosition = MyGUI::InputManager::getInstance().getMousePosition();
MyGUI::IntSize size = MyGUI::RenderManager::getInstance().getViewSize();
Ogre::Ray ray = mCamera->getCameraToViewportRay(mousePosition .left / float(size.width), mousePosition .top / float(size.height));
// ... check intersection

and for create a single round white that enlarge itself when i click?

what widget i must use? or mouspointer ? its an animation? how can i do it?

(there is a tutorial for make it?)

Depends on what you actually need. And looks like it's not about terrain at all. Could you explain better what you want as result (or find some screenshot/video of similar functionality).

this is a video of neverwinter night 2, look on ground where mouse click

Why you asking this in MyGUI forum? This is not about GUI at all. Use Mesh/Decal/particle/whatever you like.

i ask here because it seems a gui usage i ask for it on ogre forum

thanks
