First be sure that your OMNet installation is correct. try to test one of its examples (i.e tictoc). If it works, then you've done with installation. And you can create your own module. Simple way to do so: go to File -> New -> Simple Module (follow wizard sitting). Then compile your project from: Project -> Build Project.
Finally run it from: Run -> Run.
(Clean up your project first Project->Clean)
You can find very nice tutorials at omnet directory (usually C:\omnetpp-4.1\doc). Try to start with 'User guide' and 'Tictoc-tutorial'.
