Qt Creator does shadow builds by default if you don't turn that off on the second page of the new project wizard. I.e. by default it builds in a directory "projectname_somepostfix" that lies parallel to your sources.
That could be a reason for you not finding a Makefile in the project directory.
You can change the setting for an existing project in Projects mode > Build settings

Otherwise it's hard to tell what goes wrong without knowing what the errors say (e.g. from the Compile Output pane that you can pop up from a button at the bottom of Qt Creator).
