Blender over web

Hello,
I have already create a project in blender with some boutons that run script python to modeling object 3D.
Now, I want to run my project with buttons ovec the web, that’s why i install blend4web.
I want to display also my buttons or create a buttons which run my script python.
I already search on logic editor but i don’t found the solution;
Can you help me with a tutorial or an example to do this?
Thanks
