I'm new, and trying to find my way around on this website. I have a really great idea for a font, but I have no idea how to make one.

Click Tools maybe?

Try FontStruct. http://fontstruct.com

(I'm new to forum, please don't blame me if you hate FontStruct or sth :P)

We don't hate fontstruct, not at all. The limitation of fontstruct is just that it is based on geometrical components only.

Using a font creator software : http://www.dafont.com/soft.php#3
If it's just for a little work, you can use a chip software like Font Creator or Type Tools.
