You can sell one copy - but you can't prevent that customer from giving 
away copies to everyone else.  Or you can give the program away yourself 
and sell support.

If you use libraries (like the MySQL client) covered by the GPL and 
distribute the program, the entire work must be under GPL terms - 
although I think an earlier message had a link to an exception for MySql 
for some other open source license terms.
