At this point I'd suggest you go to java. It's going to be way easier to learn enough java and swing/swt and write a functional applet than it is to monkey around packing perl interpreters for PPC,Sparc,x86 and whatever else AND Tk libs AND Tk.pm into one package AND have it install, configure itself and run without benefits of the make install tests AND deal with the possibility of the user not being able to install software. It sounds like a nightmare.

This is one of the problems java was meant to solve. Java really isn't that bad. Try it.

Update:
Since the code you showed is a hello-world, I'm assuming that your app isn't written yet and you're in the planning stages. If you already have the app written, then obviously my advice isn't reasonable.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
