That is what happened. The United States had posted its Fourteen Points. Germany said it was agreeing to stop fighting and would accept a treaty based on the Fourteen Points. The fighting stopped. The powers then spent several months writing up the treaty and then presented it to the Germans. The Germans then protested they hadn’t agreed to this.
Obviously, the treaty went into more detail than the Fourteen Points proclamation but the general outline was there. The surrender of captured Russian and Belgian territory, the transfer of Alsace and Lorraine back to France, the establishment of an independent Poland with a corridor to the sea, the withdrawal from the Balkans - these were all explicitly stated in Wilson’s proclamation.
Some people have argued that Germany didn’t really want to stop the war. They were just looking for a interruption of the fighting so they could rebuild their army. They expected that the allies would suspend the naval blockade during the armistice and Germany would be able to bring in supplies and build up a stockpile. But then they found out the Allies would not stop the blockade for a ceasefire - they said the blockade would continue until the war was officially ended by a treaty.
