Not for VB6 (another answer mentions a .NET solution).
There used to be a Visual Basic 5 Control Creation Edition (CCE) that was freely redistributable, but my feeble attempts at searching have failed to find it; a non-Microsoft site purporting to have it has removed it and replaced it with a text file complaining of link abuse, and Microsoft themselves don't distribute it anymore, sadly.
The CCE can't be used to make executables, as hinted at by its name.
