Answer 1

It is a rather simple proposal... Using most any general purpose language at your disposal, be it VB, C, Java, Python... you need to:

 1. Save this text to a file 
    (alternatively, directly paste it into the source code adding
     necessary string delimitors)

 2. Write a small program which will

 2.1 Parse the input, 3 characters at a time, and convert each two Hex values
     to a byte type (a type holding 0-255)

 2.2 Write these bytes, in proper order to the output file (open as a "write
     binary" type file).

3 Run a virus scan on the damn thing (whoe knows where it's been)

4 Run this newly created binary... 

Answer 2

Useless reply: If you don't know how to write binary data, you have no business writing it to EXE files.
