It seems it fails to create the window. I'm no expert, but you should try to update your video drivers and/or Java

[Magiobiwan]

I, too am having issues getting 1.2.6b to run. I have the latest stable video drivers (13.12) for my Video Card on this computer, an AMD Radeon HD6670 and I have the latest version of Java 7 (Java 7U51), both 64-bit and 32-bit installed. This error happens with any version of Tekkit, but normal Minecraft, Tekkit Lite, Hexxit, and Voltz all work fine. Here's my crash report.

Go into your start menu
type in %appdata%
click your .minecraft or .technic folder
open options.txt
look for "advancedOpenGL"
change "true" to "false"
