Newbie: Can I open a GUI with a Jython library using a Python script within HEC-DSSVue?

[Derek Stuart]

I know some simple python but am completely new to Jython.  The reason I am asking this question on this

list is that an application I am using called HEC-DSSVue is built on Jython and allows users to implement

scripts to manipulate timeseries of data. I am writing such a script a script and I would like to open a window and ask the

user for some simple information (e.g.pathname for example).

Typically when using Python I would be able to use the Tkinter module to open a gui and ask the user for such information.  Unfortunately the python scripting available via HEC-DSSVue does not allow Tkinter.  I have seen a jTkinter module but I am distributing this to very novice users and would prefer to minimize their confusion.  I am hoping that Jython has a GUI that I can open using the python scripting abilities within HEC-DSSVue.  Can anybody point me in such a direction?  I know where the Jython libraries are but I don't know how I would call them from the python scripting language nor do I know which I would call if I knew how.  

Perhaps there is a 'hello world' script that I could start learning from?

Warmest Regards,
Derek

Not sure if this answers your question,  but the minimal bit of
dinking around with GUI's in Jython I've done, I've done with Java's
awt package.  I was able to get a little window to show up and have a
button that triggered a message on the window.

Unfortunately, I don't have the link.  I would google jython and awt
for a tutorial to get started.

Thank you Carl and Charles:

I have found success with the Swing package and the FileChooser routines.

here is an example:

import javax.swing as swing

chooser = swing.JFileChooser()

val = chooser.showOpenDialog(None);

print chooser.selectedFile.name

print chooser.currentDirectory

Warmest Regards,

Derek
