I just got a good enough PC to play with mods and I have one problem: I don't have a mods folder! I don't see why I don't but when I installed minecraft I just didn't. So I did what youtube said and made a folder called Mods. Then installed forge and put it into the mods folder. What my friend told me to do after that was she said "It should appear in the versions" but it wasn't, and that is where I am now. Please tell me what do! Oh and my os is windows 7.

One, this is the wrong place for this topic. This subforum is where mod developers post finished mods, not where you ask for help with mods. The correct subforum is Mods Discussion.
Two, Minecraft does not come with a mods folder, as Minecraft does not natively support mods. That's why Forge exists.
Three, you don't put Forge in the mods folder. Forge is meant to be applied to a vanilla Minecraft jar, and thus you need a vanilla jar already downloaded in order to use it. To get this jar, you need to set up a Minecraft profile with the appropriate version selected, then run vanilla Minecraft with that profile once to let it download the correct jar file into the versions folder. After that, just double-click the Forge jar file you downloaded and install the client version. Forge will copy the vanilla Minecraft jar and modify it into a Forge jar. The slight inconvenience at the beginning is in place to avoid distributing modified vanilla Minecraft files, which is against Mojang's EULA and therefore extremely illegal.
Once you've done that, all you need to do to start playing modded Minecraft is either create a new profile or modify an existing profile to use the new Forge jar and run it from the launcher. Forge is an API, however, and does very little by itself-- which is where other mods come in. Installing the vast majority of mods is as simple as dropping the mod file into the mods folder, although some mods are slightly more complex. Advice is to read the installation section of any mod topic carefully and check the contents of any mod you download that isn't a jar file. If it has anything but folders in it (such as jar, zip, or rar files), extract it into your mods folder. If it has a readme, do read it. A select few mods have other important instructions that need to be followed in order to work properly.
That said, if you're having this much trouble from the onset, I would recommend using the Feed the Beast launcher instead. I can't help you with that as I don't use FTB myself, but I hear it's much easier than building your own modpacks.
