Here is a short example on how to create a new Folder containing a
DTMLMethod
Assumed there is a my_html.dtml file in your product directory :

import OFS.Folder 
from OFS.DTMLMethod import DTMLMethod
from Globals import HTMLFile

dtml_template=HTMLFile('my_html',globals())

dtml_obj=DTMLMethod()
dtml_obj.id='my_html'
index_obj.manage_edit(data=dtml_template,title='Welcome Home')

folder_obj=OFS.Folder.Folder()
folder_obj.id='NewFolder'
folder_obj._setObject('my_html',index_obj)

self._setObject('NewFolder',folder_obj)
