I would recommend Collin Cunningham's capacitor video series he made for Make Magazine:
Check out ALL THE COLLIN VIDEOS! Seriously, he is very knowledgeable on all things electronic.
He has a lot of videos on simple electronic components like resistors, transistors, LEDs, and even project videos like 8x8 LED Matrices, Color Organs, and many Arduino projects.
Also, check out AfroTechMods's channel.
He has more advanced videos, but he explains things extremely well.
AfroTechMods Transistor Video:
The specific task you are trying to accomplish is more difficult than I initially thought.
I spent about 15 minutes trying to figure it out by drawing up a schematic; no dice.
However, once I tried putting together some components on a breadboard, it clicked.
I then drew a schematic using everything I had on my breadboard. Here is it:https://www.circuitlab.com/circuit/3mt4q6/two-button-solution/
I like to avoid using the diodes and the MOSFETs when dealing with simple tasks such as this one, but I couldn't see how I would do it without them.
