Is there a Java Class that generates a POM.xml file?

Question

In my job project I have recently been asked to generate POM files via a java class. The problem is that I am very, very new to Maven (like since last December).

        MavenXpp3Reader reader = new MavenXpp3Reader();
        Model pomModel = reader.read(new FileReader(pomLibFile));
        final List dependencies= pomModel.getDependencies();
        final List modules= pomModel.getModules();
        final List profiles = pomModel.getProfiles();

        InputStream inputStream = new FileInputStream(new File(pomLibFile));
        StringWriter writer = new StringWriter();
        IOUtils.copy(inputStream, writer, "utf-8");
        pomModel.getDependencyManagement();
        final Properties properties = new Properties();
        properties.load(new FileInputStream(pomProperties));
        RegexBasedInterpolator interpolator = new RegexBasedInterpolator();

        interpolator.addValueSource( new EnvarBasedValueSource() );
        interpolator.addValueSource( new PropertiesBasedValueSource( properties ) );

        List synonymPrefixes = new ArrayList();
        synonymPrefixes.add( "project." );
        synonymPrefixes.add( "pom." );

        PrefixedValueSourceWrapper modelWrapper = new PrefixedValueSourceWrapper( new ObjectBasedValueSource( pomModel ),synonymPrefixes, true );
        interpolator.addValueSource( modelWrapper );

        PrefixedValueSourceWrapper pomPropertyWrapper = 
                new PrefixedValueSourceWrapper( new PropertiesBasedValueSource( pomModel.getProperties() ), synonymPrefixes,  true );
        interpolator.addValueSource( pomPropertyWrapper );

        interpolator.addValueSource( new PropertiesBasedValueSource( properties ) );

        RecursionInterceptor recursionInterceptor = new PrefixAwareRecursionInterceptor( synonymPrefixes, true );

        String serializedPOM = interpolator.interpolate( writer.toString(), recursionInterceptor );
        System.out.println("-------- "+serializedPOM);;

though I am still stuck if I have to add multiple (unknown number of) dependencies.
