Of course it's possible. But it's harder than you probably think.

Try making a parser first and then you'll start to see the 'how hard'.

Re: create a simple programming language
For a start, try reading about Lexers, Parsers.

Lex and Yacc by John R Levine.

Also, since you are planning on building a compiler too, try reading this book:
Compiler Design by Aho, Ullman, Sethi

Re: create a simple programming language
You might want to do an easier alternative.

For example, say you write a code in a text file like so :
C++ Syntax (Toggle Plain Text)
  1. //code.txt
  2. START_PROGRAM
  3.   print "hello world"
  4. END_PROGRAM
That file contains your new programming language code. Now you can use C++ to read in the file, and parse it accordingly and do proper stuff.
