IMO, wait until you do your annuals. Those all like warm soil, and are not frost tolerant. I either WS them in late April, or direct sow them in May.

cukes and zuccini are fast growers so you will do well if you start it couple of weeks before your last frost date. Otherwise you will have to deal with too large and much more fragile plants.

Linda,
What do you mean by to large and to fragile plants?
I sowed al my cucumber,peppers and tomaotes all last week,am i in trouble now?Will they not sprout.
Sometimes i get confused,one will say it is ok to sow now,then a few days later,someone will ask the same question,and be told to wait,i know it is accourding to zone,which is what i look at,what s up with that? :0)

Here's what I do in zone 7: zukes, cukes, squash and melons (the hotties) I do two weeks before setting out. Last frost here is 4/30, but I give it two more weeks, so figure 5/15 for last frost. So...I sow these 4/30.

I only want them to sprout and NOT grow large before transplanting to minimize transplant shock.

Toms, eggplants and peppers I start indoors (noted in conversations) because I "baby" these three and want a controlled environment. That's just me.

they grow too fast and vine is fragile. If you WS them they should not germinate now so you should be safe. I would not start them indoor now. Never done WS them though.
