The actual Portal's ID is 90.
The frame of the portal, Obsidian's ID is 49.
120 is the Minecraft I.D. code for the end portal frame.
If you mean the portal ID number, it is 90.
Nether Portals are constructed from Obsidian, so that's the block you would need. The Block ID for obsidian is 49 (command /give 49 1, remove if playing single player) and a Flint and Steel to activate the portal.If you mean the end portal, the block ID for End portal blocks is 120 and you'd need Eye(s) of Ender to activate this portal.
If you mean endstone, the ID is 121
If you are referring to the Nether portal panel block, which appears when a Nether portal frame is lit, its data value (ID) is 90. When placed without being in a Nether portal frame, you can still use it, however, you cannot place 2 of the portal block next to each other, or else they will both disappear.

There is no command block in minecraft. If you go to the Minecraft WiKi it will have all the information you need for anything in the game.
The Minecraft block ID for lava is 10 or 11 for stationary and flowing lava respectively.
You could make a mould using any block that can't catch fire, and create the portal block by block first by pouring lava from a bucket into the spot you want the next obsidian block to be, then using water to turn it into Obsidian.
The only way to get a command block in Minecraft is to have cheats on in your world.Once you generated a world like that, type in the following command:/give [your Minecraft character's name] 137 [amount up to 64]That will give you a command block.
