source code for graphic symbol display and editing?

[Cobracus]

I have a need to create graphics editor to run under Windows. The graphic symbols will look somewhat like UML class symbols. One must be able to enter a name and then text elements in each of several parts of the symbol, and they must resize themselves for the amount of text.
I'm looking for source code where this is already implemented.

Failing this is there a package (eg OpenGL) with which this can easily be done - where one defines a multi-line symbol and then has the software draw instances of it.

I would really not like to implement the whole editor from scratch so some other suggestions would be welcome.

There are a few controls that you can try:
E-XD++ Library will be the best choice for you I think, at: http://www.code-home.com

Hope it is useful to you.

Wonderful to get your reply.

Sorry to say that this had to be put on the back burner, partly because of the lack of response to my query.

I have to ask: Is everyone creating their own editor and the dynamic symbols such as expanding UML class symbols? But then why isn't anything open source except OpenGL.
