Fontlab is a good app. If you are familiar with Illustrator that will help. The tutorials that come with the application are very good, so you can just flip through those. Start simple and after creating a few basic characters, export and test. Use simple characters to make easy fonts. What I can remember from my education is that we used the word OHamburgefonstiv to test those characters to see if it was all coherent enough and the spacing was correct. If all looks and feels well, I continued.
Hope this helps just a little bit for those who are willing to try.
