Well, Europe would be divided between the Greater Germanic Reich (Großgermanisches Reich), that is one super-state comprising of Hitler's Germany, The Netherlands, Flanders, Denmark, Norway and the conquered Eastern Europe. That is, the 'cleansed' Eastern Europe, now being populated by ethnic Germanic peoples.

Next to that superstate states like France, the UK, Spain and Italy and smaller states would function as puppet states. Although Hitler did hold a special place in the world for his 'Anglo-Saxon brothers' the UK. All European nations would be forcibly part of a bigger trade-union of some sorts to support the continuing war effort of Hitler.

(I'm not really an expert on the rest of Hitler's idea about his dreams of world conquest, maybe someone can give more info)
